Bitcoin and transaction costs

This is Joseph.

Mark has noted that he called the cryptocurrency bubble in advance [which makes me sound a bit dickish when you just come out and say it -- MP]. We are all aware that Bitcoin is volatile, which is a bad property as a store of value. But other stores of value are also volatile (like gold). But one feature of bitcoin seems under-reported. We know that miner rewards drop with time and that about 20% of bitcoin is "lost". The lost feature is terrible because it means the supply shrinks with time to become less and less -- in other words the currency is naturally deflationary. Deflationary is bad because it encourages holding on to money instead of spending money, which is not a good economic feature. Again, all well know issues. 

We also know about the slow transaction speed (visa does 1,700 transactions per second, Bitcoin does 4.6) which creates concern about scalability and ability to settle small transactions quickly. 

But what about transaction fees. Here is Square's transaction fees in Canada:
Square has competitive, transparent pricing so you know exactly how much you’re paying to process credit and debit cards. It’s just 2.65% per tap, dip or swipe for Visa, Mastercard, American Express and international credit cards, 3.4% + 15 cents for each card not present transaction (like Virtual Terminal), and 2.9% + 30 cents for other transactions (like invoices paid online). For debit transaction, it’s just a 10 cent flat fee for every Interac insert and tap.

Now a currency, like Bitcoin, is probably closest to Interac.  So that is about 7.9 cents in USD. What are the transaction fees like with Bitcoin? Well, they are not fixed but it is a bidding process. Looking at the past year or so we have fees like: 

  • June 13th USD$2.492 
  • June 12th USD$1.258
  • March 2nd USD$4.471

The lowest of these would be 16 times the Interac rate and would pull level with VISA at nearly the USD$100 mark. Keep in mind this is while rewards for miners are still happening so prices could still go up. 

On April 19, 2021, it reached a peak of USD58.858. 

Now consider an Interac transaction for a cup of coffee. The best coffee is starbucks [That's the only factual error in this post -- MP] and it costs $2.10 plus 13% HST tax for a cup in Ontario (specific locations may vary). An Interac card leaves the store with $2.00 revenue for the cup. Visa leaves the store with $2.04. So a profitable transaction. Now interac is currently running 7 transaction per second but it is in only one small country (Canada) with 40 million inhabitants. Bitcoin is traded worldwide. 

With a bitcoin the cost on June 13th would be about CAD$3.19 for a net loss. If the customer pays the fee then the cost of a cup of coffee, after tax, goes from $2.37 to $5.56 if you pay the average transaction fee. Paying low transaction fees may make the processing unattractive. 

How long does this take on average at the storefront with all going well? Estimates of about 10 minutes are not reassuring for a coffee shop. Small interac transfers are very fast compared to that (I find the actual interface takes 10-15 seconds to confirm). 

Other currencies don't seem to be a solution. Ethereum was USD$2.182 on June 13th, 2022 which isn't a huge advantage over bitcoin. Nor does the 30 transaction per second compare favorably to VISA. Proof of stake is interesting but one might want to wait a bit and make sure it was not vulnerable to clever coders or investors, as coding errors have caused a hard fork before

Now, keep in mind the use case of Bitcoin is as a currency and not an investment. The idea is to get in early before everyone uses it, which essentially requires it to be deflationary to make a buy and hold strategy rational. So you have a slow, expensive technology that can't solve the basic problems that paper currency can? But it is both deflationary, volatile, and hard to estimate transaction costs on. 

Are these good properties?

Journal Club: when the headline and findings diverge

This is Joseph.

This study has been making the rounds:


Now I want to be very careful here. What was the actual category (listed as #2 in the article:
The datasets are available from the corresponding author on reasonable request.

Now look at what happens:

In summary, of 1792 e-mails sent, we did not receive any response for 1538 articles because messages were not delivered (N=77; 4.3%) or the author did not reply (N=1461; 81%). Responses were received from 254 (14%) contacted authors 

So, first of all, I am not sure that we should consider the 4% who did not have a message delivered considered to be "non-compliant". That is important as the headline number of  93% did not respond includes those who were not actually successfully contacted. Of those responding, about 1/2 (122 vs 132) shared their data. 

Then we have the most common reasons:

  1. The authors asked for more information about our study, but after our detailed response and clarification, we did not receive further response from them 
  2. Their informed patient consent did not include sharing data with other researchers, or the ethical committee prohibited external data sharing and use 
  3. They cannot access the data, either because they are no longer in the institution that conducted the research, or they are no longer active on the project 
  4. They do not want to share the data or in any way participate in our study without a specific explanation
Some of these are declining to be in the study and some seem like reasonable excuses. Data often belongs to the institution and a closed down lab might have no way to get data. Still, of the responders the success rate was 48%, which seems like a reasonable level of outcome given that you are openly declaring that this is for a study and not for the research project itself.

That reminds me, what about the non-responders:
The Ethics Committee of the University of Split School of Medicine approved the study protocol. Scanned approval of the Ethics Committee was available to the study participants on request. Study participants were informed in the invitation that their response to the emailed questions is considered as their written informed consent.
So, responding to the email is considered to be consenting to the study. Which means that people who decided not to participate are being told that sending a response is considered written and informed consent. Now the sample letter they used is not yet available online, but is participating in a study mandatory

So what does Canada think about this
. . . the core ethics principle of respect for persons implies that individuals who participate in research should do so voluntarily, understanding the purpose of the research, and its risks and potential benefits, as fully as reasonably possible
What about the US NIH:

Informed Consent

The Belmont principle of respect for persons is primarily applied by requiring that all human
subjects research participants provide voluntary informed consent to participate in research.
The three fundamental aspects of informed consent are:
1. Voluntariness
2. Comprehension
3. Disclosure

And:

Potential participants must understand that enrolling in the research is voluntary and that they may withdraw from the study at any time without penalty or loss of benefits

So there are two reasons that a person could chose not to have provided data:

  1. They were not being especially honest in providing data
  2. They chose not to consent to a research study
What do the authors conclude:

In conclusion, authors of research articles are frequently not willing to share their data, even if they wrote in their manuscript DAS that they would do so. Our findings can enable the creation of new guidelines and practices in the research community to foster the availability of raw research data

It is worth also noting that they are not making the raw data available for this study, which doesn't seem to foster the availability of raw data.

We did not publish our raw data along with the manuscript because it could be understood that we are publicly shaming authors who did not want to share their data. As for the raw data that were received during this study, we informed our study participants that those raw data will be deleted after being examined and that all data and communication will be treated with strict confidence

 But putting that aside, they really can't tell the difference between choosing not to participate and declining to share data.  But they had a 48% success rate among the responders and even that denominator is shaky.

Consider items 1 and 4 of the most common reasons. How different is that from withdrawing consent from the study based on being informed? Reason #3 (lost access) seems like a pretty odd thing to frame as "not compliant" (the author's title). Reason #2 is odd but could be an issue for sharing data outside of the context of replication or exploration (what is reasonable is a very important nuance).

So all we could be discovering is that busy researchers often decline to participate in mass email research studies that involve a fair amount of labor (in this case uncompensated). Among those who had the ability to respond, I think they got better than half as reasons like the ones below may not really make sense to include in the denominator:

  • A conceptual article, no data to share
  • The author wanted ethics approval translated into English
  • They cannot access the data, either because they are no longer in the institution that conducted the research, or they are no longer active on the project
  • The corresponding author instructed us to use a web service to request the data
Is it "not compliant" if the author lost access to the data (institution being especially clear) or they wanted a web service to be used? What is really missing here is a clear statement of the estimand, which is the propensity to participate in an email study and not the propensity to share data with peers. 

In any case, this is a long discussion of an article. But the headline is getting a lot of engagement and I am not sure it can be clearly interpreted that way. A data request, as a part of research, becomes voluntary based on clear ethical principles and it seems very odd to characterize a decision not to engage as "not compliant" when you state even replying to the email is taken as informed consent. Nobody is entitled to informed consent (it's consent not obligation) and so it is utterly unclear what the rate would be in the 85% who either never got the email or chose not to consent to a voluntary research study.

Simple political analysis

This is Joseph.

As a fun palate cleanser after Mark's extremely important post, I thought that discussing this tweet would be fun. But seriously, watch the video first. 


Changing a sitting president is challenging, even if the incumbent is willing to step aside. Just for the record, there is no hint that Joe Biden is interested in stepping aside. That said, if he did, these seem to be his political weak points:
  1. Age (he will be 83 when he starts a second term). I actually think this might be his biggest vulnerability if the Republicans run somebody younger (e.g., not Trump)
  2. Inflation is always politically painful
  3. Other branches of government (primarily the judiciary but also things like the filibuster threshold in the senate).
Bernie helps with none of these. He is a year older then Biden and Biden would be starting a second term and not a first. At the end of two terms, Bernie would be over 90. Biden is well aware inflation is bad and that constrains populist plans (with inflation and interest rates rising, you need to make more serious tradeoffs which makes it hard to get a major spending program going). 

What about the courts? The Trump speed run on the judiciary is real but it isn't like Biden isn't addressing it. Despite a very narrow senate majority, he even confirmed a very competent supreme court justice with a history as a public defender. The senate is a concern as it has a skew that makes it favorable for Republicans. But I am unaware of any case where Bernie running would assist greatly with the senate races. But really that'd be the only scenario that would be at all intriguing.

Speaking of the senate, Bernie is 80 years old and will be 83 at the start of a 4th senate term in a state with a Republican governor. If we are worried about the senate then getting a strong replacement in the next two years seems far more productive.

Now, I am on record as saying it would not surprise me if Joe Biden was a single term president. He returned to political life at a time that really required somebody of his talents and background, but he is also nearly 80. Nor is this without precedent:  Lyndon B. Johnson, James K. Polk, James Buchanan and Rutherford B. Hayes were all voluntarily one term presidents (and Hayes was succeeded by another Republican so party switching is hardly a certain outcome in this small sample). 

But a replacement needs to a tell a compelling story about how they would improve the fortunes of the Democratic party. Bernie has been extremely important in setting policy priorities and will end as an extremely important senator. But he addresses none of the three main vulnerabilities and I think it is hard to see who could impact #2 and #3. So you need somebody with Joe Biden's strengths but who is less susceptible to the "sleepy Joe Biden" line of attack. But keep in mind this was not a highly successful line of attack. So options are quite limited. 

But that depends on a great many tough political decisions and a lot of things that are unknowable (e.g., what Joe Biden wants). But I see no good argument. Even Trump running again doesn't move the needle -- Biden already beat Trump and that'd be compelling psychology in a rematch.

"Legitimate Political Discourse"

Thursday, June 9, 2022

Arguments not in evidence

This is Joseph.

Mark had a pretty strong reaction to my last piece. It has been a while since we had a debate and I think this is a good place for one. Let me state, before anything else, that Mark made good points. 

But here is the thing, even though the reasons that he brings up are absolutely correct, they are not actually part of the core arguments being made by either side. I see the issue is administrative processes dragging on for very long periods of time, I think that whole new reasons becoming clear, as the megafire issue because more obvious, is actually a good example of this phenomenon. 

The environmental impact report does mention the wildland fire risk as follows:

Wildland Fires

The Project site is located in a mostly urbanized area, and is surrounded by a variety of residential and commercial/office land uses. While the majority of the surrounding area is currently developed with residential and commercial uses, uphill to the north of the Project site is an additional a roughly 4.6 acres of undeveloped privately-owned parcel land, itself surrounded by development. This relatively small and isolated wild area would not be considered a high risk for wildfires and is not in an identified high fire hazard zone, as listed in Section 5.3.1 of the General Plan. In addition, it the Project is subject to approval of the Fire Marshal as it relates to brush and vegetation removal to the north. As such, the Project would have a less than significant impact.

Now this report is from 2012; conditions may well have changed. But this is a decade ago. The real concern here is not that the development is or is not approved. It's that starting a process to determine whether it can be approved or not is still going nearly 18 years after the initial process began.  

Perhaps my first piece could have been clearer: it would be a far better world where the project was just dead after 5 years than one in which the costs can be driven up so much by legalistic delay. If the project is a bad idea then it should be canned. But it has been a decade since the final environmental report. Maybe it was botched. Maybe we know more a decade later. 

It's also worth noting the original zoning that is being challenged (i.e., what could be built without the zoning change): Professional Administrative Office. So this debate is not about protected wildland but a debate about whether this parcel of land should be a series of townhomes or an office building. Now maybe it should be protected wildland, but the process should be a lot faster, one would think, about making this determination. 

But the petition itself makes none of the excellent arguments that Mark is making (go read them first, they are smart and well taken, unlike what you are about to read):

The project as proposed would result in unacceptable adverse impacts on public safety and traffic congestion due to the increased number of vehicles attempting ingress and egress onto East Blithedale, at what is already the City’s most congested intersection.

The project proposes height, unit density, and building massing that is grossly inappropriate and out of character with the surrounding neighborhoods and structures, which would result in significant adverse visual and aesthetic impacts to those neighborhoods, and be in direct violation of the City's Design Guidelines and General Plan policies for the area.

The conclusions of the EIR that the project will have no significant impacts which cannot be mitigated, particularly with regard to traffic and visual criteria, are unrealistic and without basis in fact.

The project’s density would result in the complete loss of valuable open space, the obliteration of vegetation on the final foothill of Mt. Tam, and a loss of the aesthetic quality of the natural entry to Mill Valley.

The actual arguments are 1) traffic, 2) doesn't look nice, 3) we don't agree with the EIR's disagreement with #1 and #2, and 4) "valuable open space would be lost", which is a value to current homeowners more than anyone else. 

I would have far, far more sympathy with the arguments if they had something like "California megafires are already making this area too dense and it would be unsafe to increase density; we need to build elsewhere". But the arguments being made are what they are and the smart arguments seem to be absent. 

Perhaps this example is unrepresentative of the broader housing conversation in California. First, it is amazing how atypical San Francisco issues often are of broader CA issues. How many people would guess that the LA metro area much, much larger than SF metro area in population? Second, it would hardly be surprising for the NYT to pick the least relevant part of a problem in California. Some would say that it might actually be typical. 

But I don't see how this type of slow process is helpful to quality and thoughtful development, given the arguments being advanced. I am really unclear why the office building would improve neighborhood character as opposed to the townhouses. Or how it makes sense to block any development of somebody else's land when it was clearly zoned for development  when purchased. Maybe this is a rare and exceptional SF area problem that doesn't leak into other areas of California. 

But it is clear that housing costs are growing. Fresno has nearly doubled in cost in the past 5 years (from a bit over $200K to a bit under $400K). I think it makes sense to consider the reasons. That said, I must admit that low interest rates are absolutely for sure a bigger driver than zoning disputes.

California has a serious shortage of housing but apparently it's nothing like the New York Times shortage of straw men

 Joseph may just be trolling me here:

The recent New York Times article on the twilight of the NIMBY was interesting just for the low level of actual good ideas for why new housing is bad. The idea was to build 20 condos on a hill in a neighborhood of detached houses. 

 

While arguments given here certainly do qualify as "low-level", it's just possible that this has less to do with the quality of the potential reasons not to build this particular structure and more to do with the fact that the New York Times has gone all-in for the narrative that blames the housing crisis on hypocritical liberals in expensive neighborhoods, and we know from experience that when this paper invests in a narrative, the staff will do anything to protect that narrative up to and including sacrificing their first born.


In this case, Kirsch may be illogical, hypocritical, and selfish, but she is not wrong. It actually is a horrible idea to put more development in Mill Valley.

To understand why we don't want more people here and why Conor Dougherty's article can't be taken seriously, we need to start with wildland–urban interfaces (WUIs) "a zone of transition between wilderness (unoccupied land) and land developed by human activity – an area where a built environment meets or intermingles with a natural environment. Human settlements in the WUI are at a greater risk of catastrophic wildfire."

 As you can see, Mill Valley construction is problematic from a WUI standpoint.


Nor is history reassuring:
 

On July 2, 1929, a fire lookout on Mount Tamalpais spotted smoke rising from the railroad grade on the eastern slope. A wildfire, cause unknown to this day, had sparked on the mountain, flames blowing downhill toward Mill Valley below. Though the Great Mill Valley Fire covered a relatively small footprint, it was disproportionately destructive, burning for three days and incinerating more than 100 homes.

Sixteen years later, in September 1945, another major fire stormed through the Mount Tamalpais watershed. Dry weather and strong winds converted a pair of small brush fires into an inferno that burned more than 20,000 acres, from Lagunitas to the Bolinas Lagoon. While there hasn’t been a major fire on Mount Tam in the 74 years since, between 1881 and 1945 the area burned five times.

“Everyone thinks about that,” says Shaun Horne, Natural Resources Program Manager for the Marin Municipal Water District. Without a significant fire in decades, he says, and with the encroachment of invasive plant species, “There’s more potential fuel. It’s a high-hazard environment for wildfire.”


 

Encouraging development in WUIs is generally a bad idea for a number of reasons. It puts people in harm's way. The smoke from burning buildings is much nastier than the smoke regular forest fires (especially concerning given Mill Valley's location). Most important though is the way that moving ever more people into these areas makes the necessary political calculus all but impossible.

Arguably the biggest crisis facing California at the moment is megafires. The only way to address this crisis is by aggressively promoting the good fires which we have been suppressing for over a century (unlike the native Americans who were here first). Good fires bring with them risks and those risks are primarily focused on places like Mill Valley.

Loads of other issues with this article, too many for a post. Maybe I'll come back to it, or maybe I'll point you to some of the posts I've done on the subject in the past, all of which point to the conclusion that you should never listen to the New York Times' analysis of the California housing crisis (or any other California story).

 Remember, LAT > NYT.

NIMBY and California

This is Joseph.

The recent New York Times article on the twilight of the NIMBY was interesting just for the low level of actual good ideas for why new housing is bad. The idea was to build 20 condos on a hill in a neighborhood of detached houses. 

There ensued a decade of meetings, lots of legal back and forth, and a sign that said “Save Kite Hill.” The city also got a lot of letters. They said the project was an “insane” idea that would create “unimaginable density” and lead Mill Valley toward an “LA like destruction.”

Most of the letters raised questions about parking and traffic. Others voiced a more esoteric set of concerns, like “confusion for the post office.” One writer averred that anyone who lived in the new condos would be accepting a higher cancer risk, since their homes would be downwind from the wood-fired oven at a nearby restaurant.

Obviously, the people who currently live near the restaurant are innately immune to cancer? The post office is that understaffed that they can't add addresses? I think the real reason remains this:

“From my backyard I see the hillside,” Ms. Kirsch wrote from her Hotmail account. “Explain how my property value is not deflated if open space is replace(d) with view-blocking, dense, unsightly buildings.” 

Letting house get so expensive has been a terrible idea. It creates inequality (people who own homes gain massive profit from appreciation) and drives up housing costs in general considerably. The other reasons given for why there is a housing shortage are not compelling:

Ms. Kirsch does not deny that California has a housing problem but has a different narrative about why. In her telling the state’s problems have little to do with the lack of housing — a diagnosis that unites basically every liberal and conservative economist along with the Obama, Trump and Biden administrations — but instead blames investors who buy single-family houses, big technology companies, and inequality generally. 

Well, inequality is a factor, in that home owners become wealthier if they resist growth. Not sure how technology companies can be influencing the whole of California prices. As for investors, well an artificial housing shortage is a great way to make investment profitable.  

Now I don't live in California but the general issues here have been getting obvious. Expensive housing has numerous negative externalities and the leakage to transportation issues has not been great, either. One of the hard things with writing a piece like this is that you can really only call out the extreme cases; every housing and transit issue has local considerations and a quick overview makes no sense. It takes something like this, a small development that is unlikely to cripple a neighborhood to illustrate the problem. But that does not mean that development doesn't have costs, just that it looks like they have not been balanced.

Also, worth noting that this is a well reported California example but California is simply not the worst offender and the current list is a bit counter-intuitive. The worst ranked cities in California (Los Angeles and San Jose) are still more affordable than Hamilton, Ontario. Vancouver is far worse than Seattle, and New York City is more affordable than Seattle. More importantly, California is already moving to address housing affordability, maybe not in a perfect way, whereas I do not see this at all in the Canadian context (just look at difference in scale in this Canadian plan). 

 I worry that we'll never break this curse until real estate stop looking like a "can't lose" investment.

Despite what Delaney says, age is not a significant factor in predicting cardiovascular disease and cancer.* [Blogger took this down for some reason, so we're putting it back up]

*Among undergrad college students

[Following up on Joseph's post]

I'm know this sounds like a joke but it's really not. It's one of those ideas you learn as a sophomore then probably forget even though it's a potentially major issue that crops up frequently.

Whenever you see a claim that age or exercise or diet or whatever isn't a substantial/significant driver of something, there are all sorts of distributional assumptions lurking under the surface. The more homogenous the data set of a study is with respect to a certain variable, the less likely you are to find evidence of that variable causing anything. This is a big concern because an alarming amount of research is based on groups far less diverse than the general population. Remember the old joke about experimental psychology being a discipline built on the study of lab rats and college freshmen. 

On top of that, even if a causal relationship has a trivial impact on the general population today, that impact can grow in the future if the population shifts and distributions change. The reverse can happen as well, though that's usually easier to see coming since you start out with a known relationship. 

Like I said, this is all stat 101 stuff, long internalized by most of you reading this, but it's also one of those obvious/not obvious points that is almost never spelled out explicitly, and that's a mistake on our part.

Why do people make such a big deal over fake engineers when the real thing is so cool?

Bob Sorokanich of Jalopnik introduces is to the very cool body of work of Jam Handy

How does a car’s differential work? You probably have a vague understanding. Some stuff spins, some stuff doesn’t, and somehow, the result allows your car to drive around a curve without shredding its tires or chewing up its own guts. There are gears and other gears, and it’s basically magic. That was the extent of my own understanding, until I found this vintage educational film from 1937. It’s still the best, simplest, most immediately understandable explanation of how a differential works I’ve ever found.
...
Our instructor in this lesson is Henry Jamison “Jam” Handy, a fascinating character [You should check him out -- MP] who spent much of his career making educational films like this. Most of the time, they were cleverly-disguised advertisements — most of Handy’s automotive films were done at the behest of General Motors, while others were sponsored by Standard Oil. Regardless of the topic, a Jam Handy film starts with a simple question of “how does X work,” and answers it with clear, clever, immediately understandable visual aids. Typically, the last minute of the film is where it becomes an advertisement — for example, hyping the latest technological advancement you’ll find at your friendly neighborhood Chevrolet dealer. But everything leading up to that brief sales pitch is general-interest, brand-agnostic knowledge that’s absolutely fascinating for car enthusiasts or anyone with a curious mind.

One cool piece of trivia, before the development of the differential, early cars got around the problem of the wheels spinning at different speed by using a one-wheel drive.

The Realization


When Elon Musk first became a household name, the reaction, at least among people who were concerned about climate change and in favor of scientific research, broke down into two camps. All agreed he was a nice guy doing worthwhile work. Electric cars, solar power, rockets, what's not to like? 

There was, however, always a sharp divided over the question of Elon musk's technical expertise. The general public and far too many journalists were willing to take him at his word that he was the primary engineer and inventor behind companies like Tesla and SpaceX (not to mention PayPal).

Most engineers and researchers in relevant areas were dismissive of Elon Musk's real-life Tony Stark shtick from the beginning. One Rand researcher I spoke with at the time characterized Musk as a flake while a number of engineers pointed out that the technology SpaceX was using to land its rockets was the direct descendant of what we had used to land on the Moon fifty years ago.

Still, it was all in the service of a good cause.

Pretty much everyone started out somewhere between one of these two views and those who did not follow the story very closely tended to stay roughly where they started. But for responsible journalists working on the front lines, almost without exception, the consensus has moved steadily to a more negative opinion.

Recently, given Musk's meltdowns, various journalists and researchers have started coming forward and talking about their journey from cautiously optimistic to openly critical.

Ed Niedermeyer, who wrote the best book on Musk and Tesla, Ludicrous, started the ball rolling with a Twitter thread and an article in Slate. Both are excellent and, though there is some overlap, both are worth reading in their entirety.


...
...

On a beautiful day in May 2015, I drove the 13 hours from my home in Portland, Oregon, to Harris Ranch, California, halfway between San Francisco and Los Angeles. At the time, Tesla was touting a battery swap station that could send Tesla drivers on their way in a fully powered vehicle in less than the time it takes to fill up a car with gas. Overtaken by curiosity, I had decided to spend a long Memorial Day weekend in California’s Central Valley to see if Elon Musk’s latest bit of dream weaving could stand up to reality.

There, amid the pervasive stench of cow droppings from a nearby feedlot, I discovered that Tesla’s battery swap station was not in fact being made available to owners who regularly drove between California’s two largest cities. Instead, the company was running diesel generators to power additional Superchargers (the kind that take 30 to 60 minutes to recharge a battery) to handle the holiday rush, their exhaust mingling with the unmistakable smell of bullshit.

That one decision to go and find the truth underlying Elon Musk’s promises, rather than just take his word for it, changed my life in ways I never could have anticipated. Now, seven long and often lonely years later, the world seems to be understanding what I learned from the experience: Once you stop taking Musk at his word, his heroic popular image evaporates and a far darker reality begins to reveal itself.

 

Russ Mitchell is the head Automotive writer for the Los Angeles Times and he is one of the most respected journalist in his field.
His thread is less sweeping than Niedermeyer's but it fills in an interesting part of the story, and it raises troubling questions about how many other companies are using similar methods.

... 

...

 


The Transportation editor of TechCrunch also talks about the company punishing reporters by withholding access. 

Fred Lambert was one of Tesla's most loyal and vocal supporters.



Another common refrain is the Elon Realization, where Musk goes off script on a topic you know something about.

 

There's often a "learned phonetically" quality when Musk talks about technical concepts.

We haven't talked about the content bubble for a while...

Don't get me wrong, as a viewer, I'm pleased with all the choices, but from a business standpoint, this got silly quite a while back..




Like so much of our economy, the content bubble is largely driven by hype and CEO dick-measuring. At least in the US, the market is beyond saturated and  the present levels, let alone growth curve are unsustainable.

In other words, enjoy it while it lasts.

P.S. After scheduling this, I heard a public radio segment about Emmy season. It turns out that the people who have to watch all of these shows can't find the time to watch all of these shows.

Repost: Netflix Revisionism Warning

 And it is already getting ugly out there. The very same journalists and industry observers who missed every major development in the streaming story (content saturation, the impact of competition, the return of ad-based models, the continued popularity of older programming, the weakness of Netflix's IP library, the potential instability of hype economy business models) are starting to weigh in on the rough times at the still dominant streaming service. The good news is that the people who got it wrong are standing up and taking their lumps...

I kid, of course. I haven't seen anyone even briefly acknowledge how badly they fucked up. Fortunately, I've been taking notes for the past few years, and I'll be unrevising some of these revisionist takes. In the meantime, here are a few blasts from the past.

Arguments for a content bubble

First off a quick lesson in the importance of good blogger housekeeping. It is important to keep track of what you have and have not posted . A number of times, I've caught myself starting to write something virtually identical to one of my previous posts, often with almost the same title. At the other into the spectrum, there are posts that I could've sworn I had written but of which there seems to be no trace.

For example, living in LA, I frequently run into people in the entertainment industry. One of the topics that has come up a lot over the past few years is the possibility of a bubble in scripted television. Given all that we've written on related topics here at the blog, I was sure I had addressed the content bubble at some point, but I can't find any mention of the term in the archives.

One of the great pleasures of having a long running blog is the ability, from time to time, to point at a news story and say "you heard it here first." Unfortunately, in order to do that, you actually have to post the stuff you meant to. John Landgraf, the head of FX network and one of the sharpest executives in television has a very good interview on the subject of content bubbles and rather than "I told you so," all I get to say is "I wish I'd written that."

But, better late than never, here are the reasons I suspect we have a content bubble:


1. The audience for scripted entertainment is, at best, stable. It grows with the population and with overseas viewers but it shrinks as other forms of entertainment grab market share. Add to this fierce competition for ad revenue and inescapable constraints on time, and you have an extremely hard bound on potential growth.

2. Content accumulates. While movies and series tend to lose value over time, they never entirely go away. Some shows sustain considerable repeat viewers. Some manage to attract new audiences. This is true across platforms. Netflix built an entire ad campaign around the fact that they have acquired rights to stream Friends. Given this constant accumulation, at some point, old content has got to start at least marginally cannibalizing the market for new content.

3. Everybody's got to have a show of their very own. (And I do mean everybody.) I suspect that this has more to do executive dick-measuring than with cost/benefit analysis but the official rationale is that viewers who want to see your show will have to watch your channel, subscribe to your service or buy your gaming system. While than can work under certain conditions, proponents usually fail to consider the lottery-ticket like odds of having a show popular enough to make it work. And yet...

4.  Everybody's buying more lottery tickets. The sheer volume of scripted television being pumped out across every platform is stunning.

5. Money is no object. We are seeing unprecedented amounts of money paid for original and even second run content.

For me, spending unprecedented amounts of money to make unprecedented volume of product for a market that is largely flat is almost by definition unsustainable. Ken Levine takes a different view and I tend to give a great deal of weight to his opinions, but, as I said before, Langraf is one of the best executives out there and I think he's on to something.

Tuesday Tweets -- catching up with web3


HFSP is an acronym used typically in the crypto community against non-believers. Translates into "have fun staying poor." It makes it easy to gloat until you remember that for every asshole pushing crypto on Twitter, there were countless innocent victims.






Vocabulary quiz.
 While the scheme itself is now widely known, the general public generally doesn’t know the related term Ponzi finance, coined by the late economist Hyman Minsky. Ponzi finance is a broad term for a category of non-sustainable patterns of finance in which an enterprise can only meet its debt commitments if they continuously obtain new sources of debt financing to pay the interest rates on its existing loans. Enterprises involved in Ponzi finance constantly need to borrow at ever-increasing interest rates to pay the interest on their existing loans, thus the common cliche to describe this runaway phenomenon as “interest on the interest.”

Memorial Day Repost

 There is, of course, no such thing as the military perspective -- no single person can speak for all the men and women who have served in the military -- but if you are looking for a military perspective, my first choice would be Lt. Col. Robert Bateman who writes eloquently and intelligently on the subject for Esquire. Here are Bateman's recent thoughts on Memorial Day.

When the guns fell silent in the Spring of 1865, they all went home. They scattered across the country, back across the devastated south and the invigorated north. Then they made love to their wives, played with their children, found new jobs or stepped back into their old ones, and in general they tried to get on with their lives. These men were no longer soldiers; they were now veterans of the Civil War, never to wear the uniform again. But before long they started noticing that things were not as they had been before.

Now, they had memories of things that they could not erase. There were the friends who were no longer there, or who were hobbling through town on one or two pegs, or who had a sleeve pinned up on their chest. There were the nights that they could not shake the feeling that something really bad was about to happen. And, aside from those who had seen what they had seen and lived that life, they came to realize that they did not have a lot of people to talk to about these things. Those who had been at home, men and women, just did not "get it." A basic tale about life in camp would need a lot of explanation, so it was frustrating even to talk. Terminology like "what is a picket line" and "what do you mean oblique order?" and a million other elements, got in the way. These were the details of a life they had lived for years but which was now suddenly so complex that they never could get the story across to those who had not been there. Many felt they just could not explain about what had happened, to them, to their friends, to the nation.

So they started to congregate. First in little groups, then in statewide assemblies, and finally in national organizations that themselves took on a life of their own.

The Mid-1860s are a key period in American history not just because of the War of Rebellion, but also because this period saw the rise of "social organizations." Fraternities, for example, exploded in the post-war period. My own, Pi Kappa Alpha, was formed partially by veterans of the Confederacy, Lee's men (yes, I know, irony alert). Many other non-academic "fraternal" organizations got their start around the same time. By the late 1860s in the north and south there was a desire to commemorate. Not to celebrate, gloat or pine, but to remember.

Individually, at different times and in different ways, these nascent veterans groups started to create days to stop and reflect. These days were not set aside to mull on a cause -- though that did happen -- but their primary purpose was to think on the sacrifices and remember those lost. Over time, as different states incorporated these ideas into statewide holidays, a sort of critical legislative mass was achieved. "Decoration Day" was born, and for a long time that was enough. The date selected was, quite deliberately, a day upon which absolutely nothing of major significance had occurred during the entire war. Nobody in the north or south could try to change it to make it a victory day. It was a day for remembering the dead through decorating their graves, and the memorials started sprouting up in every small town in the nation. You still see them today, north and south, in small towns and villages like my own home of Chagrin Falls -- granite placed there so that the nation, and their homes, should not forget the sacrifices of the men who went away on behalf of the country and never came back.

To understand why Elon Musk is having such a bad month, you have to understand the role of FSD

In 2017, we talked about how Elon Musk's wholly undeserved reputation as a brilliant inventor and engineer was essential to his success.
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.

Back then we thought a market cap of $50 billion was "stratospheric." Turned out we hadn't seen anything yet.



A couple days ago, we talked about flying exoskeletons, those wild proposals (often based on old sci-fi shows) that Elon Musk uses to pump Tesla stock and, to a lesser extent, the valuation of SpaceX. For the car company, Musk has focused on three of these, only one of which, Full Self Driving (FSD), remains viable as a next big thing.






For a couple of years, cybertrucks (inspired, of course, by an old sci fi movie) were the product that was supposed to revolutionize the industry and push Tesla into the stratosphere. They were the subject of tremendous hype, but since the 2019 unveiling, multiple competitors (particularly the Ford F-150 Lightning) have beaten them to market, it is difficult to maintain the next big thing framing.

More recently, Musk has been trying to drum up excitement for a proposed Tesla robot named, of course, Optimus. The effort has not been going well. Elon is promising functionality far beyond anything we've seen, but, at the moment, the only things he has to show are some flashy CGI (much of it fan-generated) and, I kid you not, footage of a dancer in a robot suit. No one outside of the fanboys seems to be taking the robot seriously and of those who do, a disproportionate share seem to be primarily focused on its potential as a sexual partner. (this is not something you want to do a Google image search on.)


"Our cars are... semi-sentient robots on wheels"



Full Self Driving was the first one in and the last man standing. Every year for the past eight, Elon Musk has been promising that Tesla was a year or two away from level 5 autonomy. Even now, no one is close to level 5 and at no point in the past decade has Tesla been the leader in the field (currently it's not even in the top four), but that didn't stop the company from putting FSD on the road.




Is this legal? That's a topic of some debate. The regulators have been slow to move but the wheels are starting to turn. 

Russ Mitchell writing for the LA Times.

The National Highway Traffic Safety Administration currently is investigating 42 crashes involving robot-controlled automated driving systems. Of those, 35 are Tesla vehicles and seven are from other carmakers.
...
Tesla has been selling Full Self-Driving with a growing list of features since 2016. In recent years it’s been increasing the number of people it allows to use its “beta” version. In Silicon Valley parlance, beta means a program that functions but may contain bugs and isn’t ready for broad public release.

On YouTube, Tesla customers testing the technology on public roads continue to post videos that show it quickly veering into oncoming traffic over double-yellow lines, failing to stop for semi-trucks making turns in front of the vehicles, heading toward metal poles and pedestrians, and much more.

In compliance with DMV regulations, companies such as Waymo, Cruise, Argo, Motional and Zoox have used professionally trained test drivers as a safety backup while testing their own autonomous-driving systems. The companies report all crashes to the DMV and also report what are known as “disengagements,” moments when the robot system fails or otherwise faces a situation that requires human driver intervention.

Tesla’s exemption from those regulations is a matter of definitional parsing by the DMV. The agency, through public documents and prior statements by its media relations department, has said Full Self-Driving is a driver assist system, not an autonomous system.

The feature falls “outside the scope of DMV autonomous vehicle regulations” because it requires a human operator, Gordon told Gonzalez in a five-page letter in January. He noted that DMV regulations apply only to fully autonomous cars but said the agency would “revisit” that stance.

Regulators cracking down on FSD could devastate Tesla's stock, as could a sufficient amount of bad publicity.


"Crash Course" is a collaboration between FX and the New York Times, and while I'm no fan of the paper (stick with the LAT or the WP), their head automotive writer, Neal Boudette, is very good and has been one of the best reporters on this story.

We've got regulators and aggressive reporters. How about a senate candidate? Even I didn't have that one on my bingo card.


Why is FSD falling behind the rest of the pack? The long answer is very long, but the short answer is computing power and LIDAR



There is, as the saying goes, always a tweet.

We have been talking about the rise (and hopefully fall) of the Silicon Valley tech messiahs for about ten years which has required a lamentable amount of time to be spent on Elon Musk. Based on that I am reasonably certain he doesn't really understand the terms "local maximum," "neural nets," or "AI," but the valuation of Tesla depends on people thinking that he does.
