They would probably spend their money on upgrades and ways to expand their knowledge of the world around them. Of course since they were original build to serve one purpose, it might be harder for them to change their ways (programing) than standard skinbags.
I would actually be surprised if there wasnt some kind of loyalty programing installed, at least so the bot doesnt turn on it`s previous "owners", employers and makers. This of course might be scrambled through damage and so on, hell even reversed.
one might wonder what values and goals does an AI, Android and other sentient existances have beyond self-preservation. Would it seek to doublicate itself, much like the biologicals around it or something entirely different which would seem obscure and directly uncomprehensableby (Meta)humanity. I am sure that even if a bot is programed for one task, given it`s AI capabilities it can build up some byzantine plots in the end.
Oh which leads to me to one question, is there a way for Bots in SM to transfer themselves to a new "host" to prolong their existance or is the time limit final?
