The thread through all of this is that we don’t know what will happen, but we do know what could happen – we don’t know the answer, but we can at least ask useful questions. The key challenge to any assertion about what will happen, I think, is to ask ‘well, what would have to change?’ Could this happen, and if it did, would it work? We’re always going to be wrong sometimes, but we can try to be wrong for the right reasons. The point that Pauli was making in the quote I gave at the beginning is that a theory might be right or wrong, but first it has to rise to the level of being a theory at all. So, do you have a theory?
