>Thus, if the best effort a man with an IQ of 80 can do is sweep the streets, then we should give him job as a streetsweeper and not replace him with a robot. -- Assuming we _could_ replace them with a robot, this would seem to imply that the person is truly without use but that we are providina a made-up task in order to make this person feel 'useful'. They might as well be tieing and untieing knots on a piece of string, leading an existence depending on the generosity of others. I am not sure if there is a better definition for 'society would be better off without them', even if this is hidden from them. I am all for finding useful tasks a human of IQ 80 (whatever that means) can accomplish, but withholding progress and providing a fraudulent sense of accomplishment does not strike me as the most respectful approach one can take towards solving this problem.
