Me: There’s more than just P != NP that defeats trying to catch a flying ball by predicting where it will land and going there. Or, for that matter, trying to go there by computing a series of muscular actions and then doing them.
Caledonian: You DO realize that some humans are perfectly capable of accomplishing precisely that action, right?
People can catch balls. Nobody can do it by the mechanism described. Fielders in ball games will turn away from the ball and sprint towards where they think it will come down, if they can’t run fast enough while keeping it in sight, but they still have to look at the ball again to stand any chance of catching it. The initial sense data itself doesn’t determine the answer, however well processed.
When what you need is a smaller probability cloud, calculating the same cloud more precisely doesn’t help. Precision about your ignorance is not knowledge.
