"A GA isn't enough to do high level planning" It's quite surprising how much can be done by a GA, especially on a computer where more alternatives can be considered per unit time. One of my brothers learned to fix cars via GAs. I remember the first time he tried: armed with only a screwdriver and his statement "There are only 3 screws on this damn carburetor; there must be some way to tune the thing!" The other brothers, taught by our father the intricacies of mechanics, laughed derisively. Nowadays he's not afraid to replace struts or overhaul the top-end of an engine. I stand in awe, both of my brother and the effectiveness of GAs (otherwise know as "trial and error"). While perhaps not the fastest path to a solution, they usually get the job done.
