Yes, that's the big question. I believe that they do provide value, and have kind of a network and brand effect. I believe there's some margin for Lyft/Uber to exist. How big it will be? Who knows. Maybe not enough to support their gigantic valuation, but probably some valuation. I think many of these IPO's are simply way overvalued and are going to have trouble maintaining value. They might crash if there is a stock market tumble as the wind comes out their sales. The difference between now and 2000 however is that these are actually viable business at least on some level.
