It's a fun debate, one that comes up with regularity at start-up parties, investor conferences and even on our own network. The reality is that certain markets that are raging hot today will eventually fizzle, laying waste to millions of venture dollars, while other bets that seem crazy now will explode, perhaps turning into the next Microsoft or Google.

CNBC officially opened its San Francisco bureau (dubbed CNBC@1Market) last week, and amid the festivities, brought tech entrepreneurs and investors into its studio to sit on the hot seat.

We also wanted to know, in this environment, what technologies they view as overhyped and underhyped.

Eakin's comments came just after Twitter announced that its Periscope service reached 1 million users in its first 10 days, surpassing Meerkat, which debuted to plenty of hype at South by Southwest in March.
