> People don't want 5000 sq ft anymore. I looked at suburban houses as an option and was thinking I hope I never have enough crap to fill this much space. I think I can comfortably fit my family of 4 in 1200 sq ft indefinitely and never own a car.

That's an incredibly broad overstatement. There are plenty of people, including "techies," who still want a suburban home with a car.

There's a lot of talk in this thread that assumes that tech workers all want to live a minimalist lifestyle in a dense urban area (or even worse: that they should want to live that way). That's frankly false. I assume what's really going on is that people are projecting their parochial preferences onto a large group that's much more diverse than they understand.
