.@mattcohler says lack of aspiration = minimizing risk, not maximizing revenue/value. That's simplistic. It's probably an effeciency frontier.
Maybe he thinks that message is too complex for an on-stage discussion, but I don't. Entrepreneurs and investors should be aiming to maximize return divided by risk, shifting the curve up and to the left on that graph. It seems like the whole brouhaha about the role of Y Combinator, superangels, and entrepreneurs "not aiming high enough" is actually VCs complaining about companies and investors that are filling in gaps on the left part of the efficiency frontier. Market forces are not an aspiration problem.
