I don't buy any of this. Growing up everyone around me saw the city as somewhere you begrudgingly went out of necessity and only lived there if you had no choice, and I'm inclined to agree. In virtually every aspect I find more countryside-ish living much more pleasant.
Consider virtual reality and remote work. I imagine much of the workforce will move to virtual offices in the near to medium-far future when corporations finally come around to realizing they don't have to waste so much money on rent. There's no need for programmers, graphic designers, reporters, and employees of lots of other professions to work in a physical office. So really, as cities become less of a necessity to certain jobs, I expect a moderate exodus to nicer areas, halting growth or even decreasing population in urban centers.
