I actually think that a bit of so-called "depressive realism" is in order. Sure, it needs to be tempered with some optimism, but you need at least one guy with the winter-traveler insight and the courage to say, "Groupon for cat food sounds like a terrible idea!" Sadly, people like us are not well-received because we tend to haul out the truth when it's not wanted.
But yes, a less-bitter version of you might be a good EIR, although I think it usually comes from "founder of a company funded by the firm has a midsize exit", not out of the blue.
So you have to be born into the club to have that option? Not surprising.
Like I said, the future's not going to come from the people born into VC connections. I don't know where it's going to start and when, but I'm optimistic enough to believe that Real Technology is coming back. I see it already, but not in the high cost-of-living areas.
