Couple of snags with A.I.: with their zero movement, they have to be built where you want them but right now it means they're not actually allowed to join a colony or change profession. Or am I just doing it wrong? The other thing is that purchasing an AI on Earth is incredibly cheap (1350, I think it was) so as long as they can bought and loaded into a ship and dropped appropriately into a colony, it doesn't make much sense to build them yourself on anything but an inland colony. You could remove them from the purchase list, but I think even if you found a way around the profession problem, you could still shuttle them from place to place in ships... unless they, say, took 7+ cargo spaces or something uncarryable?
