It seems bad appartments are leading entire generations into thinking all appartments have to be terrible, last-resort options. I'm renting a recently renovated appartment , and while it's not perfect, the sound isolation is so good, that my roommate can play games with voice chat and I can sleep in the next room. Only a ~5cm wall separates our rooms.

I think a future with comfortable, large, isolated apartments is possible, and even such "fancy" apartments are going to be cheaper than full houses, if there are enough of them.
