There is a certain mindset that you find in pretty much all fields of applied mathematics (engineering, statistics, computer science, etc.), at least among the competent. It's a tendency to think in terms of complex systems, ranges,constraints, trade-offs. Musk does exactly the opposite. He seems to believe that evaluating a design is done by taking a bunch of numbers, picking the best ones and shoving them together.
That compares an average speed with a top speed, and a real-world number with a theoretical number. One input: what's the throughput of an exit? You can't squirt those pods onto a street one a second at 155 mph.— Benedict Evans (@benedictevans) June 4, 2019
This wouldn't be so bad if Elon Musk were just another clueless CEO, but the myth of the real life Tony Stark has been so internalized by journalists, investors and politicians that it has started to warp our discourse and decision making.
