Doing GAs right can be very hard. Like, I've seen cases where GAs hooked up to a certain type of physical simulation learn to exploit the ODE in play and find optima that are based on ODE artifacts, not reality. Eg wind turbine design and CFD modeling. I remember one specifically learned in Quake to always strafe run because the dx+dy gave sqrt(2) max speed instead of just max speed. What most people don't understand about GAs is that asking the question correctly and unambiguously can be harder than solving the problem. GAs can have a steep price, it's not magic.
