This week promises to offer us visions of a brighter future from the big brains on stage at the Web 2.0 Conference.  While some will likely compete for the honor of "most quotable", I'm looking for truly new ideas, perhaps even forecasts from madmen.

I would also be interested in hearing a few worst-case scenarios for the future we're building now…not to be a pessimist but rather to balance out the hype with some views on the potential damage that will surely unfold as this revolution continues.
