I see no sign that these are significant impediments to the usefullness
of GA/GP's. CPU time appears to be the biggest problem. Last I heard, Koza
had a 64 processor system, and was waiting hours if not days for a typical
run to finish.
And of course, translating abstract problems into fitness functions
is not a trivial programming task.
