This is very interesting, but of course who (aside from art students) would want to do this? If you make a piece of autonomous software (a bot) that can earn its own money, why let it keep it, spend it, and live its own weird little bot life?
Also, nobody says that such a bot wouldn't be profitable. It could send dividends to the creator (or do something else worthwhile with the money - a'la trust funds), it's just that the creator wouldn't be able to modify or stop it any more.
