"It's as though the superposition is all there in all its reality. ..The quantum reality was in a superposition. ..Retrocausality...But somehow it's as though it acts backwards...If you consciousness is something like this then that means you can retroactively, in a sense, affect something...when you think about a pianist playing some very complicated piece of music and the little finger has to decide which key to hit well that which key to hit it could be pre-programmed by then in some sense but is there any control over the sort of mood that he's going to be put into the playing which is controlling what that finger does in some detailed way I think there would be something consciously controlled and that conscious control could be making a decision between superpositions which have not yet resolved themselves into one on the other and that can happen in this retroactive way okay that's a thing that I'll leave it with you it's certainly a view which needs a lot of thinking"
