^^Very true. But there's also the ongoing urban trauma that must be dealt with as well. When the industrial revolution got going the city was a miserable place to live and urban living wound up with a bad rap ever since. The 50s didn't help either when contractors got major incentives to build in far flung areas- utilizing cheap, temporary, junk architecture- at the cost of allowing the city to rot and become ghettos. The result is that any mention of returning to traditional "cities" immediately conjures up visions of Judge Dredd as per miraclefan's response. Which is certianly understandable, but not true. There is no reason that, with proper planning, Detroit for example couldn't be as beautiful as Paris or Prague 50 years from now.
