Isn't there a pretty solid argument to be made that hyperloop (and especially what Boring Company is actually building) is so dumb that it shouldn't seriously be treated as a good faith solution and other motivations should be considered?
I don't agree. The whole Hyperloop thing was not an alternative implementation it was a pitch for a completely different society altogether. Instead of moving everyone in California at a reasonable price, let's have a giant infrastructure that is at least as large and disruptive as rail but only serves a tiny slice of the ultra-rich, everyone else has to take a car.
It wasn't "how to do it better" it was an attempt to reframe the entire question of whether medium-distance mass transportation should exist.
I don’t know where you’re getting this from. The idea has nothing to do with only serving “a tiny slice of the ultra rich”. You’re adding all this dramatic extra stuff about society and reframing.
