The CSS of Tomorrow
Predicting the Future “Television won’t last. It’s a flash in
the pan.” - Mary Somerville
Predicting the Future “Home taping is killing music” - BPI
Predicting the Future “There’s no chance that the iPhone is
going to get any significant market share. No chance.” - Steve Ballmer, 2007
I Predict: Cynicism “That sounds cool but it's useless because
we'll have to wait for browsers to catch up.”
