The comparison to the previous tech bubble isn't fair though. A lot of these companies are actually profitable and the capital cost is far lower than it was a decade ago. That is not to say that things aren't overvalued. But bubble behavior relies on investors investing in things because other people are investing in them so the price bubbles up ("housing is never a bad investment!"). I'd say that, while some of the valuations are high, a lot of these companies are at least profitable, which is more than we can take away from the previous bubble. Prices may end up settling down, but at the end of the day I'd say value is created so it's not too bad.
