Darwinism may be a fine theory in other contexts, but in startups, intelligent design works best.

I think markets are often not thinking on a long-time horizon, I think that our government structurally is doing even less so. When we have a government where we have people who are up for election at most once every six years for a U.S. senator, that's a time horizon that is much shorter than in a market that a company is looking at 10, 15, 20 years which is a time horizon over which a stock price is typically valued.
