@thomasfuchs and yes, we don't fully understand the human brain, but that doesn't mean physics doesn't apply. that's the same logic people use wrt perpetual motion machines and such nonsense; "oh, we don't fully understand it, that means anything's possible".
no. it does not mean anything is possible. nor is there any reason whatsoever to believe human brains are in any way special. they're bags of chemicals. really complex bags of chemicals, but still bags of chemicals, not magic.
