"Making money" is only a relevant goal when you need money to persuade humans to do things for you. Once you have an army of robot slaves ... you've rendered the whole concept of money irrelevant.

Or maybe a better skynet / slave army kills your skynet / slave army, but tough tits, sucks to be you and rules to be whoever's skynet killed yours.
