I have a suspicion that housing will stop being a crisis due to a combination of:
1) the main expense is the land, the houses themselves are cheap, so anything that causes existing-but-undesirable houses to now be in a commuter zone increases useful supply
2) self-driving vehicles will allow people to commute while asleep or doing their hobbies (this is a terrible idea with current tech, people already get in trouble for doing both in existing self-driving cars)
3) remote working (we already have a lot of digital entertainment and socialising)
If I’m wrong, I expect it to be because all this makes meatspace location into an even bigger status symbol than it is already.
