I'd bet it's somewhere in between. I think the determining factor is nuisance. People will put up with certain long commutes and high prices for a given reward.

I'd bet it's somewhere in between. I think the determining factor is nuisance. People will put up with certain long commutes and high prices for a given reward. If tech makes it so we can accommodate more people going further at the same nuisance level, we'll probably do that instead of the same number of people at a lower stress level. People will keep moving in until it gets shitty enough to overcome their desire to be here, right? If so, then the level of shittiness is constant over time and tech.
