Standard model for AI

Standard model for AI is human specifies the objective like here’s the discounted sum of rewards machine says okay I’m on it right now we know this model doesn’t work because we can’t specify the objective correctly and I should mention it’s not just our model this is the same model as control theory where you minimize the cost function in statistics you minimize risk in operations research in fact this is borrowed from operations research you maximize the discount of some rewards and economics you maximize a welfare function or GDP or profit or whatever objective it is all of these are the same basic standard model and it’s a bad model and King Midas could tell you that because he said okay here’s my objective I want everything I touch the turn to gold the machine said righty-ho in fact it was the gods in his case.
