Eric Levitz: "On Climate, Sanders and Warren Must Go Nuclear"

At the moment, the debate about the biggest problem facing our planet is centered on a masturbatory exercise over the appropriate tone to use when discussing the crisis, as if finding the right wording was either a necessary or sufficient condition for solving a problem. We do not have time for this.

This, on thee other hand, we should make time for. You don't have to agree with Levitz here, but you need to hear him out.

To honor its commitments under the Paris Agreement, the U.S. will need to slash its carbon emissions by at least 2.6 percent a year, every year, between now and 2025. Our nation has never come close to decarbonizing at that rapid of a pace. What’s more, to keep our promise — without making life worse for ordinary Americans — we will need to achieve such unprecedented emission cuts while sustaining economic growth and political stability. Of the United Nations’ 193 member states, 192 have never pulled off anything like that.

But France has. In fact, it pulled off something better: Between 1979 and 1988, the French cut their carbon emissions by an average annual rate of 2.9 percent. Over that same period, France reduced the carbon intensity of its energy system by 4.5 percent, by far the largest decline any country has achieved in a single decade. And it did all this without abandoning economic growth, or having to found a sixth republic, or even seeing its streets vandalized by anarcho-populists in yellow jackets.

Given the scale of this success — and the dearth of other precedents for rapid decarbonization — you might think that the French model would boast a central place in the Democratic Party’s 2020 climate debate. If so, you would be badly mistaken. France’s energy policy in the 1980s may be an exceptionally encouraging precedent, but it was also a centrally planned energy transition that involved replacing the bulk of that nation’s electricity providers with state-owned nuclear power plants. And that is an ideologically displeasing model for centrists and (some) leftists, alike.
...
Nuclear power plants currently meet about 20 percent of America’s electricity needs, making it by far the largest source of non-carbon electricity in our country. As we’ve seen, nuclear energy was responsible for the most successful decarbonization effort in recorded history. The UN Intergovernmental Panel on Climate Change (IPCC) has identified four model pathways for avoiding more than 1.5-degree warming. Three involve increasing nuclear’s share of primary energy provision by between 150 and 500 percent, while the other envisions keeping its share about where it is now. Sanders and Warren defend the expansiveness of their climate agendas on the grounds that the IPCC’s findings demand nothing less. And yet, their ostensible support for phasing out nuclear is antithetical to that organization’s own recommendations (as is Sanders’s opposition to investing in carbon capture).

It is extremely expensive and time-consuming to build new nuclear power plants. Thus, one can reasonably insist that the necessary funds would be better spent on other green initiatives. But there is no credible argument for decommissioning existing plants. And if the crisis is as severe as Sanders, Warren, and the United Nations suggest, then there isn’t really a credible argument against throwing at least some public capital at “Hail Mary” advanced nuclear technologies like small-scale reactors that could — at least theoretically — deliver safe, affordable nuclear energy at scale. The technology is simply too promising to ignore, especially considering the current limitations of renewables. As science writer (and democratic socialist) Leigh Phillips notes, “Nuclear power has an emissions intensity as low as that of onshore wind … but unlike wind can power hospitals 24/7.”

Of course, Nissan never bolted wheels to the sides of a Leaf and ran it down a tunnel, so they're still behind on that front

There was from the beginning a tendency to cut Elon Musk considerable slack for the bullshit because it seemed to be in the service of good causes such as space exploration, electric vehicles, and solar energy, but it was recognized as bullshit. When you got past the fanboys, serious, knowledgeable people never bought into the narrative. In emails and private conversations, they’d describe Musk as a “flake,” point out his habit of taking credit for other people’s work, remind you that most of the breakthroughs consisted of incremental improvements on decades-old tech (much of which had been liberated from TRW).

Eventually it became apparent that turning a blind eye to even seemingly benign crap can have consequences, particularly when it enables a charismatic con man with a messiah complex, but by the time the dangers became evident, the myth was too entrenched and (just as importantly) too well constructed. The lies reinforced each other. Dating back to PayPal, every accomplishment of his career had been inflated, so that now each new impossible claim was followed by a list of all the impossible things Musk has done before.

One of the key steps for the building of this myth has been equating electric vehicles with Tesla. The rise of the EV is a good thing in the short term and an inevitability in the long term (barring some big and completely unexpected breakthrough). Musk’s company made some important contributions in terms of technology and, more importantly, brand (all joking aside, opening the midlife crisis market to  EVs was a big deal)

But all too often the press treated Tesla as the EV company. Nissan (in some ways just as major a player) went largely unmentioned. Models from other companies that predated Tesla were ignored, as was ongoing work across the industry. All of this created the impression that Musk and associates had an enormous lead which helped push the stock price into the stratosphere and helped shore up the myth of the “real life Tony Stark.”

From Michael J. Coren:

    Yet Tesla’s ambitions will require more than owning the US market. Overseas, the Nissan Leaf remains the world’s most popular electric car. It has racked up 400,000 in cumulative sales, Nissan announced this March, and is on track to hit half a million next year. Since 2013, the Leaf has averaged about 50,000 in annual global sales, a number that surged to more than 85,000 in 2018.

    Unlike Tesla, Nissan has manufacturing plants around the world. Three of them, in Japan, England, and the US (Tennessee), produce the Leaf, allowing the hatchback to be modified for local markets. To keep costs low, much of the tooling and assembly lines exist in shared facilities. That’s kept the Leaf’s price at $29,990 for a standard 2019 model, and as low as $11,000 for a used model from 2015.

    While Tesla flaunts its style, Nissan owes its success to those low prices and functionality. The dynamic playing out in the global EV market resembles the war over smartphones. Apple has grabbed the high-end of the market with powerful, high-priced iPhones running its iOS operating system, while Google’s Android owns most of the rest. There’s a stark domestic and international split in market share. In the US, Apple has about 40% of US mobile operating systems. Overseas, Android commands 76% thanks to its functional, low-cost appeal (eclipsing Apple’s 22% share).
Of course, being the Apple of EVs would normally be a good thing, but when expectations are this high, any reasonable outcome is a letdown.

Thinking about how times have changed

This isn't a sentiment you associate with Southern Rock these days.





Hand guns are made for killin'
They ain't no good for nothin' else
And if you like to drink your whiskey
You might even shoot yourself
So why don't we dump 'em people
To the bottom of the sea
Before some ol' fool come around here
Wanna shoot either you or me

Mr. Saturday night special
You got a barrel that's blue and cold
You ain't good for nothin'
But put a man six feet in a hole

We need to talk more about WeWork.

God knows, we've said our share of mean things about Uber and Lyft and Netflix and Tesla, but for all of the confusion and myth-making that drove those valuations to their current sky high values, even I have to admit that there was at least the possibility of the promise of something big behind each of those companies. The rise of the smartphone made new models of personal transportation possible. We can argue whether the dominant business model will be all-you-can-stream or a la carte or heavily tiered or advertiser-driven, but there is little question that more and more video viewing will be done online. The future of cars is both electric and autonomous.

By comparison, you almost have to admire the pure distilled bullshit of WeWork. There is nothing to ground this business model, no recent or even promised technological advance, no big innovation, nothing but the CEO babble and Ted Talk happy speak so in vogue in Silicon Valley these days.

Here via Brad Delong, Ben Thompson spells out the inevitable corruption and self-dealing that goes with this sort of scam.
 

The tech industry generally speaking is hardly a model for good corporate governance, but WeWork takes the absurdity an entirely different level. For example: WeWork paid its own CEO, Adam Neumann, $5.9 million for the 'We' trademark.... WeWork previously gave Neumann loans to buy properties that WeWork then rented. WeWork has hired several of Neumann’s relatives, and Neumann’s wife would be one of three members of a committee tasked to replace Neumann if he were to die or become permanently disabled over the next decade. Neumann has three different types of shares that guarantee him majority voting power.... Neumann has already reportedly cashed out 700 million of his holdings via sales and loans. Everything taken together hints at a completely unaccountable executive looting a company that is running as quickly as it can from massive losses that may very well be fatal whenever the next recession hits.... The WeWork bull case and bear case... both are the logical conclusion of effectively unlimited capital. The bull case is that WeWork has seized the opportunity presented by that capital to make a credible play to be the office of choice for companies all over the world, effectively intermediating and commoditizing traditional landlords. It is utterly audacious, and for that reason free of competition. The bear case, meanwhile, is that unlimited capital has resulted in a complete lack of accountability and a predictable litany of abuses, both in terms of corporate risk-taking and personal rent-seeking...

Has it really been just two years since Bodega Vending forever disrupted retail?


I don't remember what brought it to mind but I got to wondering what happened to Bodega, the company that was going to revolutionize the convenience store industry and kill off the mom-and-pop store. The short answer appears to be nothing much. They appear to have burned through their PR budget about a year ago. Other than a few stories when they changed their name to the incredibly bland Stockwell, they have basically dropped of the map.

The company is still a going concern but it appears not by much. They only have presences in four cities though they promise more are coming "(very) soon." The website (which looks like something form GoDaddy) doesn't have a lot of details past that. It does have a jobs page with eleven listings of which seven are part-time.

All of which is making Helen Rosner look pretty good about now.

Fighting Gresham's law of journalism -- more "yes, it is just a god damn vending machine" blogging

Just to review, a few days ago, there was a great deal of fanfare around an article by Elizabeth Segran from Fast Company magazine entitled:

Two Ex-Googlers Want To Make Bodegas And Mom-And-Pop Corner Stores Obsolete

At the risk of belaboring the obvious, the article was a bad piece of business and technology journalism. It credulously accepted what should have been incredible claims from an entrepreneur with an enormous interest in hyping the story. The response was largely divided between writers who were understandably offended by the cultural insensitivity and those who unquestioningly accepted the idea that a line of low functionality vending machines (no refrigeration, no hot food or beverages, not set up for cash transactions) presented an immediate threat to convenience stores and other small retail outlets. More than a few commentators managed to fall into both camps.

The problem here is not that all of the coverage of the Bodega Vending Machine Co. was bad; it is that the bad got most of the oxygen. This is primarily a business story (the technological aspect is trivial), and it has produced some excellent business writing, but it appears that the coverage is another example of Gresham's law of journalism: the crappy crowds out the good.

The best of the clear eyed analyses probably comes from  Helen Rosner, a smart, knowledgeable writer who explained in crushing detail the major flaws in the Bodega business plan.
Bodega’s product is, fundamentally, a vending machine. (Well, maybe it’s a mini-bar — open access to product, in fancy places, with a presumed audience that’s affluent and design-minded.) Vending machines are a unique form of commerce, mostly defined by the lack of human interaction at the point of transaction. This kind of unmanned retail operation has a long history (the vending history timeline on the website of NAMA, the National Automatic Merchandising Association, kicks off with Egypt’s Ptolemaic dynasty; it is delightful), with efficiency as its primary appeal. A tiny, self-contained store without an employee saves all sorts of overhead: Less required real estate, lower payroll, shockingly greater likelihood that shoplifters will be crushed to death.

These efficiencies aren’t gravy, though; they’re essential. They work by way of a simple economy of scale: If you run a few dozen machines (or a few thousand), it becomes possible to buy your products at a discount, to warehouse the products more effectively, and to both fill and repair your vending units in a more streamlined way. These businesses live or die by logistics.

This is where things seem likely to fall apart for Bodega. Even with their wifi connections and app-connected camera sensors, the units themselves are still just offering consumers a basic model of unmanned commerce — only with smaller, fancier machines to process the transactions. What Bodega does offer as a differentiator are the number of unique products per unit (100, the average vending machine has 20-40), and the promise that the products will not just be tailored to their general environments — protein bars in the gym, tampons in a sorority house — but to their specific users. A promise of “machine learning” will, as Fast Company explains, “constantly reassess the 100 most-needed items in that community.”

At 100,000 units — the scale McDonald and Rajan envision — that’s ten million items that are active at a time, plus reserve products for restocking, plus new products to introduce as the “machine learning” (I’m sorry, I just can’t) cycles out low performers. Across specialized markets and user-informed preferences, the number of SKUs (industry shorthand for a stocked product, rather than an individual unit of that product) that Bodega would be dealing with would quickly climb into the thousands.
...
Labor is not a minor issue, with a company like this one. “Unmanned retail” isn’t a precisely accurate phrase: There may not be a person ringing up your transaction, but there are plenty of people working to maintain a system that allows that absence — even the famous midcentury automats were just the outward storefront of a working, fully-staffed kitchen. Bodega’s warehouses will need to be staffed. The trucks will need to be driven. The Bodegas themselves will need to be manually restocked — each can, bottle, and box placed one by one onto each unit’s shelves. Many traditional vending machine companies employ restockers who double as machine repairers. Will a Bodega restocker be trained to fix a busted computer-vision camera?

Rosner closes with a wonderfully pithy and honest summary of what is probably Bodega's real business plan.
In Silicon Valley, Bodega’s success will not be measured by how well it truly replaces the stores it wants to eliminate — by how many lives it makes better, how many jobs it creates, how many communities it strengthens, or how many families it serves. Like most startups, its success will depend on whether its founders and investors make money, either by cashing in with an IPO or selling to a bigger company for a tidy profit.

It's true that you regret things you didn't do more than things you do. Think of all of the mean things I could have been saying about WeWorks.


Nocera has long been one of the best on this beat.


Important to note that many of the areas most vulnerable to tropical cyclones also have the lowest coastal elevation.




 





 

The damage done by the lapses at the New York Times  is greatly exacerbated by its standing as the paper of record. If the paper and The Washington Post would switch positions in just this one aspect, it would do a tremendous amount of good.


Along the same lines.

Look for the Union Label


The ILGWU sponsored a contest among its members in the 1970s for an advertising jingle to advocate buying ILGWU-made garments. The winner was Look for the union label.[9][10] The Union's "Look for the Union Label" song went as follows:

    Look for the union label
    When you are buying a coat, dress, or blouse,
    Remember somewhere our union's sewing,
    Our wages going to feed the kids and run the house,
    We work hard, but who's complaining?
    Thanks to the ILG, we're paying our way,
    So always look for the union label,
    It says we're able to make it in the USA!

The commercial featuring the famous song was parodied on a late-1970s episode of Saturday Night Live in a fake commercial for The Dope Growers Union and on the March 19, 1977, episode (#10.22) of The Carol Burnett Show. It was also parodied in the South Park episode "Freak Strike" (2002).

Townsville has always been a hub of evil science innovation


From Gizmodo:
There’s a certain allure to the geoengineering approach, particularly from the techno-optimist mindset that’s in vogue in Silicon Valley. Keeping the planet at an optimum temperature while humanity gets its shit together with carbon emissions can feel somehow more attainable than doing the hard work to cut emissions. A giant space mirror to reflect sunlight—something Yang said was among his top choices for cooling the planet because it’s reversible if something goes wrong on Earth—is a lot sexier than a closed coal plant.
“If you were to launch a satellite with expandable mirrors and you can make it so that you can bring a satellite back down if you want,” Yang said. “If you find that it’s effective, then great or if you find that is useless, then you don’t use it but then there’s no harm done.”

One of the contradictions of Silicon Valley visionaries (of which Andrew Yang is at least an honorary member) is how often the absolute faith in science and engineering to solve problems is associated with a surprisingly weak grasp of the subjects. The initial reaction to this phenomena is to assume there has to be more to it than that, some cool detail like a Lagrangian point, not enough to make the proposal feasible but at least enough to make it interesting.

But there is seldom more than meets the eye, the big, wildly ambitious ideas generally come down to nothing more than tired old sci-fi movie tropes.

If we are going to talk about giant space mirrors, we might as well do it right. Thank god for the comment section.

This is a lot of money for an awfully short suborbital flight.

From Space.com
SpaceShipTwo is designed to be lofted by a carrier plane called WhiteKnightTwo. At an altitude of about 50,000 feet (15,000 meters), the space plane separates from the carrier; then, SpaceShipTwo engages its onboard rocket motor to make its own way to suborbital space.

Passengers aboard the vehicle will experience a few minutes of weightlessness and get to see the curvature of Earth against the blackness of space before coming back down to Earth for a runway landing.

A ticket for this ride currently costs $250,000, and more than 600 people have put down deposits to reserve a seat, Virgin Galactic representatives have said.

With all the hype, it's important to remember how little there is here. Technologically there's nothing groundbreaking while as a business model, it does offer a spectacular view and a few minutes of weightlessness, but there are other options for the latter and plenty of spectacular views closer to home, all available at a fraction of the cost. The main selling points appear to be novelty and bragging rights, both of which are likely to fade well before the investors (at least those at the back of the line) see any returns.

Bethany McLean made her name covering Enron, which is never a good sign

There's a major expose out from Vanity Fair on SolarCity. Give a read. We'll talk more later.

A few points to keep in mind when reading any upcoming story about Elon Musk

First, a quick update from the good people at Gizmodo, specifically Ryan Felton:

Elon Musk awoke on Thursday with the intention of sending Twitter into a frenzy by declaring that he received “verbal govt approval” to build a Hyperloop in the densest part of the United States, between New York City, Philadelphia, Baltimore, and Washington D.C. This is dumb, it’s not how things work, and requires, uh, actual government approval.

Felton goes on to contact the government agencies that would absolutely have to sign on to such a project. Where he was able to get comments, they generally boiled down to "this is the first we're hearing of it." The closest he came to an exception was the federal Department of Transportation, which replied

We have had promising conversations to date, are committed to transformative infrastructure projects, and believe our greatest solutions have often come from the ingenuity and drive of the private sector.
This is a good time to reiterate a few basic points to keep in mind when covering Elon Musk:

1.    Other than the ability to make a large sum of money through some good investments, Elon Musk has demonstrated exceptional talent in three (and only three) areas: raising capital for enterprises; creating effective, fast-moving, true-believer corporate cultures; generating hype.

2.    Though SpaceX appears to be doing all right, Musk does not overall have a good track record running profitable businesses. Furthermore, his companies (and this will come as a big slap in the face of conventional wisdom) have never been associated with big radical technological advances. SpaceX is doing impressive work, but it is fundamentally conventional impressive work. Before the company was founded, had you spoken with people in the aerospace community and asked them "what is closest to being Mars ready, who has it, and who are the top people in the field?", the answers would have been the type of engine SpaceX currently uses, TRW (which sued SpaceX for stealing their intellectual property), and the chief rocket scientist SpaceX lured away from TRW. By the same token, Tesla is pretty much doing what all of the other major players in the auto industry are doing in terms of technology.

3.    From the beginning, Musk has always had a tendency to exaggerate and overpromise. Smart, skeptical journalist like Michael Hiltzik and the reporters at the Gawker remnants have taken any claim from Elon Musk with a grain or two (or 20) of salt.

4.    That said, in recent years things have gotten much, much worse. Musk has gone from overselling feasible technology and possibly viable business plans to pitching proposals that are incredibly unlikely then supporting them with absurdly unrealistic estimates and sometimes mere handwaving.

5.    The downward spiral here seems to have started with the Hyperloop. This also seems to be the point where Musk started trying to do his own engineering rather than simply taking credit for the work of those under him. On a related note, it is becoming increasingly obvious that Elon Musk has no talent for engineering.

6.    Musk’s increasingly incredible claims have started to strain the credulity of most of the mainstream press, but the consequences have been too inconsistent and too slow-coming to have had much of a restraining influence on him. Even with this latest story, you can find news accounts breathlessly announcing that supersonic travel between New York and DC is just around the corner.

7.    Finally, it is essential to remember that maintaining this “real-life Tony Stark” persona is tremendously valuable to Musk. In addition to the ego gratification (and we have every reason to believe that Musk has a huge ego), this persona is worth hundreds of millions of dollars to Musk. More than any other factor, Musk’s mystique and his ability to generate hype have pumped the valuation of Tesla to its current stratospheric levels. Bloomberg put his total compensation from Tesla at just under $100 million a year. When Musk gets tons of coverage for claiming he's about to develop telepathy chips for your brain or build a giant subterranean slot car race track under Los Angeles, he keeps that mystique going. Eventually groundless proposals and questionable-to-false boasts will wear away at his reputation, but unless the vast majority of journalists become less credulous and more professional in the very near future, that damage won’t come soon enough to prevent Musk from earning another billion dollars or so from the hype.

The hyperloop is a masters' class in controlling the narrative

Here's how you do it.


1. Set the topics

For a brief window a few weeks after the initial white paper, boosters of the hyperloop completely lost control of the narrative. Papers like the Washington Post published devastating takedowns which left no stone upon stone of the original proposal and the whole thing seemed dead in the water.

The lull would prove temporary and when the story returned, the pro hyperloop camp pretty much got everything they wanted in terms of setting the agenda. There were speculative pieces about what life would be like in a world of supersonic ground transportation. Stories about new startups and impressive-sounding rounds of funding. Breathless accounts of demonstrations that were limited strictly to the parts of the system that were already widely in use elsewhere. Skeptics were relegated to a paragraph or two, almost always will below the fold.


2. Create the laws-of-physics standard

Promoters of the hyperloop have managed to introduce what is almost certainly the ultimate in low bars for infrastructure proposals, the assertion that it does not violate the laws of physics.

This takes on an added degree of absurdity when applied to a maglev vactrains,  an idea that engineers have been playing around with for at least 100 years, longer if you break it down to its component parts


With no one in all that time seriously questioning its theoretical foundations.

Nonetheless, it has become one of the standard tropes of the here-comes-the-hyperloop article to haul out a physicist who assures the readers that magnetic levitation works and that vehicles traveling in vacuums don't have a problem with air resistance.




3. Work the people covering the story.

The supporters played on the press's weaknesses for tech messiahs and opinions differ journalism. There is a intense desire to believe that things like supersonic trains and Mars colonies and immortality formulas are not just possible but are right around the corner. If anything the Press is particularly susceptible to this, especially when the idea was associated with some Silicon Valley savior.

Most of the reporters on this beat were also notably weak on the subtleties of engineering. Even the best of them tended to think in terms of principles to be explained rather than problems to be anticipated, understood, and solved. Issues that would be top-of-mind for any mechanical or civil engineer like thermal expansion were almost entirely off of their radar unless one of the experts they consulted brought it up.

4. Wait out the critics

Of all the weapons in the promoter's arsenal, patience was perhaps the most valuable. With only occasional exceptions, they ignored their critics and eventually the reporters did too.

5. Keep funding "private" until actual money is involved

At first, the hyperloop was supposed to be so cheap to build and maintain that it was hardly worth talking about. Just charge passengers twenty bucks a head and you'd break even in no time. The development costs were all being handled privately. Even if the plans never came to fruition, what was the harm?

The suggestion that little or no tax dollars would be involved further shielded the proposals from scrutiny, letting them gain credibility simply by going unquestioned for so long in the public discourse. Then, slowly but inevitably, the idea of public funding started to ease its way into the conversation. Now it's public-private partnerships.  Care to guess what the next point on the line will be?

"A public-private partnership" ... nothing ominous about that phrase

Just so we're clear. We are edging closer to see hundreds of millions, perhaps billions of tax dollars go to highly dubious projects, not because the promoters have introduced major technological breakthroughs or have proposed well thought-out plans, but because they managed to wait out their critics, counting on reporters' eagerness to believe a too-good-to-be-true story and reluctance to do the hard work of digging into the complex engineering details.  Yes, there have been exceptions, but by now they are all but drowned out by the hype and bullshit.


Ryan Kelly, Head of Marketing and Communications for Virgin Hyperloop One, told CU that the next major step is to build what the company calls a “certification track.”

That track would be a little over seven miles long and would enable the company to go beyond what it has achieved at its privately-funded test track. That means putting people in the pods for the first time, developing a switching system that would allow multiple pods to travel in the tube at the same time [I'm not sure about this part. I think the switching system may be for allowing the pods to take different forking paths. -- MP], and seeing if a pod can safely travel through the tube at a much greater speed than it has so far (to achieve the kind of travel times the company has promised, pods would have to travel more than twice as fast as the XP-1 did in Nevada).

...

Officials in India recently announced that a proposed Virgin Hyperloop One project connecting Pune and Mumbai will be moving into the procurement phase, although Kelly said that the company has not yet decided where to build the certification track.

“Whether India is going to be able to provide the support in order to certify globally (is still unknown)…the U.S. I think has a better opportunity to potentially do that and so that’s why states are kind of vying for that now,” he said, adding that the company estimates the cost of building the track in India at “about $500 million.”

“Our timeline here is that we want to have the certification track up and running by 2024, somewhere in the world, and we want (the Hyperloop) certified and ready to go,” Kelly added, explaining that, even if the track is not built in Ohio, the planning and procurement process for the Chicago route could continue for the next five years, and, once the technology is certified and approved, “we break ground.”

An estimate of the overall cost of a Hyperloop connecting Chicago, Columbus and Pittsburgh has yet to be released, but a study by the Colorado Department of Transportation put a $24 billion price tag on a 325-mile network in that state.

As for who would pay for the $500 million certification track needed to prove the technology works, Kelly said “we’re looking at a public-private partnership; (there will be) private investment, but whatever that public agreement looks like would have to be negotiated case-by-case…so, we’re also looking for, obviously, what’s the best offer that we’re going to get to make this happen?”

One more thing.

One of the advantages of having been blogging this long is that when someone says something really stupid, you've probably already written a rebuttal

For example, say that a Washington Post columnist/torture enthusiast/Manafort minion (or Stone crony -- I'm not entirely clear on that point) starts pontificating about kids these days...


 

I don't have to spend my evening writing a post explaining why you can safely skip all of these op-eds about millennials. I can just dip into the archives.

Among living Americans, there are only two "generations"

 "The ________ Generation” has long been one of those red-flag phrases, a strong indicator that you may be about to encounter serious bullshit. There are occasions when it makes sense to group together people born during a specified period of 10 to 20 years, but those occasions are fairly rare and make up a vanishingly small part of the usage of the concept.

First, there is the practice of making a sweeping statement about a "generation" when one is actually making a claim about a trend. This isn't just wrong; it is the opposite of right. The very concept of a generation implies a relatively stable state of affairs for a given group of people over an extended period of time. If people born in 1991 are more likely to do something that people born in 1992 and people born in 1992 are more likely to do it than people born in 1993 and so on, discussing the behavior in terms of a generation makes no sense whatsoever.

We see this constantly in articles about "the millennial generation" (and while we are on the subject, when you see "the millennial generation," you can replace "may be about to encounter serious bullshit" with "are almost certainly about to encounter serious bullshit"). Often these "What's wrong with millennial's?" think pieces manage multiple layers of crap, taking a trend that is not actually a trend and then mislabeling it as a trait of a generation that's not a generation.

How often does the very concept of a generation make sense? Think about what we're saying when we use the term. In order for it to be meaningful, people born in a given 10 to 20 year interval have to have more in common with each other than with people in the preceding and following generations, even in cases where the inter-generational age difference is less than the intra-generational age difference.

Consider the conditions where that would be a reasonable assumption. You would generally need society to be at one extreme for an extended period of time, then suddenly swing to another. You can certainly find big events that produce this kind of change. In Europe, for instance, the first world war marked a clear dividing line for the generations.

(It is important to note that the term "clear" is somewhat relative here. There is always going to be a certain fuzziness with cutoff points when talking about generations, even with the most abrupt shifts. Societies don't change overnight and individuals seldom fall into the groups. Nonetheless, there are cases where the idea of a dividing line is at least a useful fiction.)

In terms of living Americans, what periods can we meaningfully associate with distinct generations? I'd argue that there are only two: those who spent a significant portion of their formative years during the Depression and WWII; and those who came of age in the Post-War/Youth Movement/Vietnam era.

Obviously, there are all sorts of caveats that should be made here, but the idea that Americans born in the mid-20s and mid-30s would share some common framework is a justifiable assumption, as is the idea that those born in the mid-40s and mid-50s would as well. Perhaps more importantly, it is also reasonable to talk about the sharp differences between people born in the mid-30s and the mid-40s.

There are a lot of interesting insights you can derive from looking at these two generations, but, as far as I can see, attempts to arbitrarily group Americans born after, say, 1958 (which would have them turning 18 after the fall of Saigon) is largely a waste of time and is often profoundly misleading. The world continues to change rapidly, just not in a way that lends itself toward simple labels and categories.

The essential takedown of the Mars delusion

If you have followed this story at all, you have to read this article by George Dvorsky.
The Red Planet is a cold, dead place, with an atmosphere about 100 times thinner than Earth’s. The paltry amount of air that does exist on Mars is primarily composed of noxious carbon dioxide, which does little to protect the surface from the Sun’s harmful rays. Air pressure on Mars is very low; at 600 Pascals, it’s only about 0.6 percent that of Earth. You might as well be exposed to the vacuum of space, resulting in a severe form of the bends—including ruptured lungs, dangerously swollen skin and body tissue, and ultimately death. The thin atmosphere also means that heat cannot be retained at the surface. The average temperature on Mars is -81 degrees Fahrenheit (-63 degrees Celsius), with temperatures dropping as low as -195 degrees F (-126 degrees C). By contrast, the coldest temperature ever recorded on Earth was at Vostok Station in Antarctica, at -128 degrees F (-89 degrees C) on June 23, 1982. Once temperatures get below the -40 degrees F/C mark, people who aren’t properly dressed for the occasion can expect hypothermia to set in within about five to seven minutes.

Mars also has less mass than is typically appreciated. Gravity on the Red Planet is 0.375 that of Earth’s, which means a 180-pound person on Earth would weigh a scant 68 pounds on Mars. While that might sound appealing, this low-gravity environment would likely wreak havoc to human health in the long term, and possibly have negative impacts on human fertility. 
...

Pioneering astronautics engineer Louis Friedman, co-founder of the Planetary Society and author of Human Spaceflight: From Mars to the Stars, likens this unfounded enthusiasm to the unfulfilled visions proposed during the 1940s and 1950s.

“Back then, cover stories of magazines like Popular Mechanics and Popular Science showed colonies under the oceans and in the Antarctic,” Friedman told Gizmodo. The feeling was that humans would find a way to occupy every nook and cranny of the planet, no matter how challenging or inhospitable, he said. “But this just hasn’t happened. We make occasional visits to Antarctica and we even have some bases there, but that’s about it. Under the oceans it’s even worse, with some limited human operations, but in reality it’s really very, very little.” As for human colonies in either of these environments, not so much. In fact, not at all, despite the relative ease at which we could achieve this. 


It goes on from there, demolishing the whole ridiculous sham. If we had a functional discourse, this would kill the topic of imminent Martian colonies and let us move on to a serious conversation about the exploration of space.

Of course, we don't have a functional discourse.

This won't kill the topic.

We won't move on.

Respectable publications like the Atlantic will continue to run articles like CSI:Mars. Elon Musk will continue to be treated as a tech messiah. Actual breakthroughs like airbreathing rockets will go largely unnoticed.

And we will all continue getting dumber by the day.

After following Uber and Lyft, it's almost refreshing to find a tech company that's competent at being evil

Back in Arkansas, we used to talk about Wal-Mart "killing a town twice." The company would open a store in a small town, drive the local merchants out of business, then close that location so that the residents would have to do their shopping at the Wal-Mart in the next town ten or fifteen miles down the road.

The underlying logic remains the same. If you have market dominance and deep pockets, your quickest path to higher profit margins is to drive the little guys out of business. The complete lack of shame does, however, seem to be a bit of a 21st Century innovation.

From Gizmodo.

Citing interviews with merchants of the e-commerce giant, as well as internal sent alerts to those individuals, Bloomberg reported Monday that Amazon is effectively penalizing its sellers if it finds that their products are being offered for a lower on rival websites. If it finds competitive pricing elsewhere, Amazon alerts a merchant with price comparisons between the two marketplaces and informs them that their product has essentially been demoted by Amazon’s system and will be more difficult to find or purchase on its site, according to the report.

Bloomberg said the practice began in 2017, but added that alerts have been more frequent as Amazon works to maintain its dominance in the e-commerce space.

The way that Amazon works to undermine sales for merchants of competitively priced products is to remove the “Buy Now” button that appears to the right of products on its platform, Bloomberg reported. While the product can still technically be purchased, it makes the product more difficult for shoppers and can hurt a seller’s bottom line. It also means that sellers are being forced to adjust their prices on rival marketplaces, which can be a blow to any attempts to offset the huge chunk of change that Amazon takes for itself just to list merchant products on its site.

“Amazon works hard to keep prices low for both customers and sellers. We have very competitive fees for sellers and we make significant investments on their behalf to continually improve our store and empower their businesses,” a spokesperson told Gizmodo in a statement by email. “In our store, we feature the offer that predicts the best shopping experience for the customer based on a number of factors including price and delivery speed. Sellers have full control of their own prices both on and off Amazon, and we help them maximize their sales in our store by providing them insights on how to be the featured offer.”

Of course, Amazon controlled just under half of the e-commerce market as of last year, and it only gets bigger every day—meaning online sellers have few places to go to find a customer. And with online markets hollowing out the brick and mortar space, online sellers don’t really have a choice to not be online. This kind of practice might keep prices down for consumers and users glued to Amazon dot com, but it does not create healthy competition or a sustainable marketplace for sellers.

Agent-based simulations and horse-race journalism

[This was never my area of expertise, and what little I once knew I've mostly forgotten. Since lots of our regular readers are experts on this sort of things, I welcome criticism but I hope you'll be gentle.]

I tried a little project of my own back in the early 2000s. One of these days, I'd like to revisit the topic here and talk about what I had in mind and how quixotic the whole thing was, but for now there's one aspect of it that has become particularly relevant so here's a very quick overview so I can get to the main point.

Imagine you have an agent-based simulation with a fixed number of iterations and a fixed number of runs. You randomly place the agents on a landscape with multiple dimensions and multiple optima and have them each perform gradient searches. Now we add one wrinkle. Each agent is aware of the position of at least one other agent and will move toward either the highest point in its search radius unless another searcher it is in communication with has a higher position in which case it heads toward that one.

What happens to average height when we add lines of communication to the matrix? At one extreme where each searcher is only in contact with one other, you are much more likely to have one of them find the global optima but most will be left behind. At the other extreme, if everyone is in contact with everyone, there is a far greater chance of converging on a substandard local optima. Every time I ran a set of simulations, I got the same U-shaped curve with the best results coming from a high but not too high level of communication.

It is always dangerous to extend these abstract ideas derived from artificial scenarios to the real world, but there are some fairly obvious conclusions we can draw. What if we think of the primary process in similar terms? Each voter is doing an optimization search, bringing in information on their own and trying to determine the best choice, but at the same time, they are also weighing the opinions of others performing the same search.

Given this framework, what is the optimal level of communication between voters via the polls? At what point does the frequency of polling reach a level where it makes it more likely for voters to converge on a sub-optimal choice? I'm pretty sure we've passed it.

America is a country bitterly divided into two groups – – treatment and control.

The following would sound paranoid if it hadn't been so openly discussed by the leaders of the conservative movement in real time. At the risk of slightly oversimplifying, during the flush years of the Reagan administration, these leaders came up with a multipart plan to address the challenge of maintaining power in America while pursuing policies that lacked majority support.

The plan included devoting resources to high value-to-cost races such as midterms and statehouses, gerrymandering and voter suppression, dominance of and greater freedom to use campaign money, a highly disciplined carrot and stick approach to the establishment media that played shrewdly on its weaknesses and biases, and a massive social engineering experiment.

The pundit class has always had a problem with acknowledging and honestly addressing the various aspects of this plan, but it is the last element which indicates the largest blind spot. Commentators and more embarrassingly even some political scientists have pushed a string of theories that don't come close to fitting the facts with at least one requiring that West Virginia be re-assigned to the Confederacy.

All of this flailing around might be excusable if there were not an obvious explanation that almost perfectly describes the data. At least on a high level, all you need to ask yourself is who got the treatment?

Yes, there are certainly complications and complexities that need to be addressed. We need to talk about why certain people respond better. We need to look at the various channels and mechanisms beyond media including Astroturfing and the corruption of many of the leaders of the evangelical movement (particularly those espousing prosperity gospel). We need to acknowledge that this is not a clean experiment and that there are multiple levels of selection effects to contend with.

Those details, while important, are secondary. For now, the point we need to focus on is that there is a remarkably strong correspondence between conservative media reaching critical mass and an area going deep red, pro-Trump.

Unquestionably, the causal arrows run both ways here and we should approach some of the more subtle questions with caution, but the highly simplified model – – conservative propaganda and disinformation are the primary drivers of the rise of the reactionary right – – does an extraordinarily good job in explaining the last decade and the reluctance of many commentators and researchers to embrace it is itself a social phenomenon worth studying.

Rational actors, stag hunts and the GOP

We have hit this idea in passing a few times in the past (particularly when discussing the Ponzi threshold), but I don't believe we've ever done a post on it. While there's nothing especially radical about the idea (it shows up in discussions of risk fairly frequently), it is different enough to require a conscious shift in thinking and, under certain circumstances, it can have radically different implications.

Most of the time, we tend to think of rational behavior in terms of optimizing expected values, but it is sometimes useful to think in terms of maximizing the probability of being above or below a certain threshold. Consider the somewhat overly dramatic example of a man told that he will be killed by a loan shark if he doesn't have $5000 by the end of the day. In this case, putting all of his money on a long shot at the track might well be his most rational option.

You can almost certainly think of less extreme cases where you have used the same approach, trying to figure out the best way to ensure you had at least a certain amount of money in your checking account or had set aside enough for a mortgage payment.

Often, these two ways of thinking about rational behavior are interchangeable, but not always. Our degenerate gambler is one example, and I've previously argued that overvalued companies like Uber or Netflix are another, the one I've been thinking about a lot recently is the Republican Party and its relationship with Trump.

Without going into too much detail (these are subjects for future posts), one of the three or four major components of the conservative movement's strategy was a social engineering experiment designed to create a loyal and highly motivated base. The initiative worked fairly well for a while, but with the rise of the tea party and then the Trump wing, the leaders of the movement lost control of the faction they had created. (Have we done a post positing the innate instability of the Straussian model and other systems based on disinformation? I've lost track.)

In 2016, the Republican Party had put itself in the strange position of having what should have been their most reliable core voters fanatically loyal to someone completely indifferent to the interests of the party, someone who was capable of and temperamentally inclined to bringing the whole damn building down it forced out. Since then, I would argue that the best way of understanding the choices of those Republicans not deep in the cult of personality is to think of them optimizing against a shifting threshold.

Trump's 2016 victory was only possible because a number of things lined up exactly right, many of which were dependent on the complacency of Democratic voters, the press, and the political establishment. Repeating this victory in 2020 without the advantage of surprise would require Trump to have exceeded expectations and started to win over non-supporters. Even early in 2017, this seemed unlikely, so most establishment Republicans started optimizing for a soft landing, hoping to hold the house in 2018 while minimizing the damage from 2020. They did everything they could to delay investigations into Trump scandals, attempted to surround him with "grown-ups," and presented a unified front while taking advantage of what was likely to be there last time at the trough for a while.

Even shortly before the midterms, it became apparent that a soft landing was unlikely and the threshold shifted to hard landing. The idea of expanding on the Trump base was largely abandoned as were any attempts to restrain the president. The objective now was to maintain enough of a foundation to rebuild up on after things collapsed.

With recent events, particularly the shutdown, the threshold shifted again to party viability. Arguably the primary stated objective of the conservative movement has always been finding a way to maintain control in a democracy while promoting unpopular positions. This inevitably results in running on thinner and thinner margins. The current configuration of the movement has to make every vote count. This gives any significant faction of the base the power to cost the party any or all elections for the foreseeable future.

It is not at all clear how the GOP would fill the hole left by a defection of the anti-immigrant wing or of those voters who are personally committed to Trump regardless of policy. Having these two groups suddenly and unexpectedly at odds with each other (they had long appeared inseparable) is tremendously worrisome for Republicans, but even a unified base can't compensate for sufficiently unpopular policies. Another shutdown or the declaration of a state of emergency both appear to have the potential to damage the party's prospects not just in 2020 but in the following midterms and perhaps even 2024.

So far, the changes in optimal strategy associated with the shifting thresholds have been fairly subtle, but if the threshold drops below party viability, things get very different very quickly. We could and probably should frame this in terms of stag hunts and Nash equilibria but you don't need to know anything about game theory to understand that when a substantial number of people in and around the Republican Party establishment stop acting under the assumption that there will continue to be a Republican Party, then almost every other assumption we make about the way the party functions goes out the window.

Just to be clear, I'm not making predictions about what the chaos will look like; I'm saying you can't make predictions about it. A year from now we are likely to be in completely uncharted water and any pundit or analyst who makes confident data-based pronouncements about what will or won't happen is likely to lose a great deal of credibility.

Catharsis

Picking up from our previous post about approaching the rise of the Trump voter in terms of a social engineering experiment, one of the best indicators of epicyclic thinking is that each adjustment helps explain only one isolated aspect of the situation. In contrast, when introducing a good framework or mental model, most of what we see should suddenly make more sense. This applies not only to what happens but to how it happens.

With that in mind, let's talk about something that has been largely absent from the various think pieces on the subject but which has great explanatory power and which rises naturally from the social engineering framing: catharsis/emotional release.

If we start with the compound hypothesis that conservative movement propaganda and disinformation has driven a significant portion of the population (let's call it 20 to 40% just to have a ballpark) into a highly unpleasant state of stress and cognitive dissonance and that these people gravitate toward and reward anyone who relieves this emotional tension, either through message, affect, or language.

Consider affect for a moment. From the standpoint of someone who has spent the past few years or even decades hearing a relentless gusher of stories about welfare cheats and foreign criminals and persecution of Christians and countless other threats and outrages, a politician like Mitt Romney seems so bizarrely out of touch as to suggest collaboration or some form of mental illness.

For people in the treatment group, politicians like Trump and members of the tea party provide an enormous sense of emotional release because finally the leaders of the party are saying what the subjects see as appropriate things in an appropriate manner. For the most part this seems to be because this new crop of politicians also received the treatment.

I don't want to get too caught up in the finer distinctions between catharsis, emotional release, relief of stress, etc. What matters is that the conservative movement has spent more than a quarter century using distorted news and disinformation to cultivate a base motivated by anxiety bordering on panic and anger bordering on rage. It is easy to see why the leaders believed that having a base this motivated and hostile to the opposition would be to their advantage. It is not so easy to see why they believed they could control it indefinitely.

I have to admit I winced a little when he made the guided missile comparison

One of the things that always strikes me when looking at these fifties predictions for the future of space travel is how much Apollo scaled back those ambitions, despite costing perhaps double what people expected.

Tesla's claims are not just unbelievable; they aren't even internally consistent

Over at Jalopnik, Aaron Gordon has an excellent rundown of the Boring Company's Las Vegas tunnel project, but the most important section focuses on another part of the Elon Musk organization. [emphasis added]

So, we’re supposed to believe Teslas will be capable of full-self driving in all conditions by next year even though, by the following year, a safety driver will be needed for a .8-mile tunnel with a dedicated right-of-way, the single simplest application of self-driving that could possibly exist.

Not only does this lend serious doubts to the Tesla robotaxi promise, but it is also a definitive step backwards from better, existing technology.

Airport people movers, close relatives to whatever the hell The Boring Company is building in Las Vegas, have been driverless for decades. Just last month, for example, I had a lovely, quick journey on Denver International Airport’s driverless people mover, which opened in 1995.

Yet here we are, in 2019, and The Boring Company says they’ll need a driver for their people-mover which moves fewer people over a shorter distance for “additional safety.”

But, hey, 1 million robotaxis on the road by next year. If you can’t believe Elon Musk, who can you believe?

For those who haven't been following this story, Musk's claim that a fleet of Tesla robotaxis is just around the corner is a perhaps essential part of the justification of the company's stock price. The audacity was remarkable, even for him. To run an Uber-type service without human backup drivers requires complete level-5 autonomy, and that appears to be years away.

Though not quite bullshit free, compared to a standard Musk spiel, the Las Vegas project has to be grounded in reality. There are actual contracts and deliverables to consider. In other words, this is what Tesla promises when they know they'll be held accountable.
