One of the biggest signs of the bubble were the lack of sanity on exits and IPOs for unproven businesses and technologies.

In this case there is certainly (some) irrational exuberance for funding, but unless you start seeing lots of minimal revenue IPOs it's not the same animal.

In short - lots of startups may die, but it's probably more things that wouldn't have otherwise been funded. It's unlikely to crash the stock market again at current rates.
