With 400 mile range (soon), state willing to give 1 lane each way to self-drive cars at 120mph, why build HSR? Waymo would be green, *point-to-point* in <3.5 hours, connect to small towns, much lower fixed cost, identical peak capacity (assume German "halber Tacho"), similar MC
This will have a bunch of second-order effects, e.g. 1. A big decline in traffic accidents and fatalities, 2. More people willing to live and commute further from city centers, changing land values 3. Increased congestion leading to the need for congestion pricing, 4. The

Thinking about this issue as an economist, I think an underappreciated dimension is that the absence of the SAT/ACT in the college application process is itself a cause of K-12 grade inflation. The absence of the SAT made grade inflation a more powerful lever through which high

it is amazing to me that there are any universities still not requiring standardized tests
the ucsd story was way worse than what i gleaned from the tweets, a whole public education pathway appears to have broken down because it's optimized around not having the appearance of inequity instead of teaching people things

Like so many other things, Andrew Gelman got to the idea of "decorative statistics" first. https://t.co/QjiynYPOYC
