I accept that hardware a problem for human tech but I still think it is more than that;
I understand a flies brain has only a few thousand neurons a PC CPU has billions of transistors (if my figures aren't exact forgive me)
A flies brain manages all its life task - recognize predators, food, mates manage it metabolism and some impressive flight maneuvers and all done autonomously.
Computers do some impressive things but I don't believe we can do the equivalent even if we had a trillion transistors
