Professor Gerard 't Hooft - Determinism all the way

Audio becomes intelligible at 20:20

I find this video almost impossible to follow due to the sound quality. Still, I know the basic argument anyway. If we have nonlocal activity, then cause and effect would appear to be interchangeable unless we come up with one of two answers: (1) Superdeterminism says that the experimenter is not free to choose the angular settings of the detectors. Everything is predetermined in some great conspiracy since the dawn of time. I think this is what "determinism all the way" is advocating. (2) Superrandomism says that the Lorentz transformation that we think we can do to exchange cause and effect is a piece of metaphysics. With any real Lorentz transformation the nonlocal random event that we are trying to catch out will be ancient history by the time we complete the Lorentz boost and we will be on to a new uncorrelated random event at best. This can be represented in a computer simulation by providing a button to do a Lorentz boost which reseeds the random number generator in use as a side effect. I call this the Protean system and it cannot be beaten. We can get on with trying to simulate nonlocal phenomena and at least we don't need to fret about causality. There are plenty of other problems like the Courant-Friedrichs-Levy condition. Notionally the RNG will be the Mersenne twister, but taken in conjunction with the Protean system it becomes a real RNG which is up to reliable Vernam cipher standards. We can always XOR the RNG with other types of RNG. For example in the Cambridge area Premium Bond numbers are available via a classical interface at the rate of two a second, and we can use an RNG which uses the Mersenne twister in half second bursts and reseeds itself by reference to PB numbers. I would express the hope that CUPS would give publicity to more than one point of view at the moment since nothing is settled.

It seems an interesting talk, but what is more interesting is that there are so few comments/reactions to it, why?

Everyone is watching string theory.

the audio is unintelligible

Awesome 🙂❤️

The non-intelligible part is only repeating what Einstein has been saying also: That quantum mechanics cannot be complete and that reality must be fundamentally deterministic. So you can skip to the intelligible part for the crux of the presentation.
