Ben Thompson and Doug O'Laughlin (

I think even Byrne Hobart would agree (from his interview with Ben):

Bubbles are this weird financial phenomenon where asset prices move in a way that does not seem justified by economic fundamentals. A lot of money pours into some industry, a lot of stuff gets built, and usually too much of it gets built and a bunch of people lose their shirts and a lot of very smart, sophisticated people are involved with the beginning, a lot of those people are selling at the peak, and a lot of people who are buying at the peak are less smart, less sophisticated, but they’ve been kind of taken in by the vibe and they’re buying at the wrong time and they lose their shirts, and that’s really bad.

This is a classic bubble. It starts, builds, and ends the same way. The technology is valuable, but it gets overbought/overproduced. Still no telling when it may pop, but remember asset values across many categories are rich right now and this could hurt.
