I think the usage of the term "bubble" could use a little sharpening. In this context, for example, you could also use "gold rush" for an entirely different (yet similarly vague) effect.
Bubble implies an overall deflation. Gold rush implies a few people will get rich--especially those selling tools--and the rest will go belly-up. The latter seems more plausible in general. And, honestly, gold rush probably applies better to a lot of things in tech than bubble. (Though dot-com was probably more of a bubble even if some companies came out the other side.)
