The Field of Dreams conceit is especially popular in Silicon Valley, where engineers are biased toward building cool stuff rather than selling it.

Thinking about how disturbingly herdlike people become in so many different contexts - mimetic theory forces you to think about that, which is knowledge that's generally suppressed and hidden. As an investor-entrepreneur, I've always tried to be contrarian, to go against the crowd, to identify opportunities in places where people are not looking.
