MIT just built an AI that can control your body.It can move your fingers, make you play piano, even if you don’t know the song! AI decides the hand movement. Wrist pads send signals to your muscles, so your fingers move even if you don’t know how

This is probably AI, but there are pools that are actually that deep. And once you reach a certain depth, your body will not automatically float back up to the surface. You will start getting pulled down deeper and deeper by gravity.
