I've worked a decent bit with stochastic search (not necessarily just EAs/GAs but also Metropolis-Hastings and extensions of MH) and the search process tends to favor probabilistic and inaccurate individual units but gangs many of them together for reliability.

This is wholly different from how we view computer programs today. It may work, but you'd better have a good application in mind, otherwise you'll get laughed/shooted out of the room.
