Oh yeah it wouldn't change a god damn thing, arguing about it would be literally pointless. Same thing as arguing against free-will, either it exists or it doesn't. Debating it is pointless, finding out one way or the other is pointless since in both cases nothing changes.

No no this is plain WRONG :( These “super determinists” need to read Gramsci and understand that the subject IS NOT a slave!!

Not really sure why people think so poorly of physical determinism. Why do people think that if the universe were to be put into the same state twice then we would get two different 'histories' of its states from that point on?

This is just incorrect, read theory

that's not what I read at all. Physical "determinism" is something I actually believe in and it's entirely different from the idea that the universe itself "knows" what's going to happen. Regular physical determinism can't explain faster than light information sharing in quantum physics- Regular physical determinism would assume that the "normal" physical laws interacting is what would predetermine anything, which can't explain faster than light interaction without some extra part. Superdeterminism seeks to be the belief that either the universe intrinsically "decides" everything that will happen before it does, or has some sort of weird invisible law dictating it, separate and superceding from the laws of physics that we know, including quantum physics. Hence the "super". All you described was normal determinism (which is still fucked over by quantum physics even if superdeterminism is real because it just doesn't make sense for anyone to be able to physically understand how superdeterminism works. What would happen if we did? We would act on information about what we find out happens but we would be super-determined by the universe to do that but we would be able to see that because we figured it out so we would act on the fact that the universe decided we would act on it but that would be decided by the universe too so we would see that because... which is different from normal physical determinism because each realization is arguably explainable by physical processes and isn't pre-determined, just inevitable due to physics.)

Some Redditor:

Superdeterminism is dismissed because it is not a "useful" theory. It can't be falsified, but in a superdeterministic universe falsification itself would not be real. The fundamental process of science would not be "real" in any meaningful way. In a superdeterministic universe, the outcomes of experiments no longer reveal anything about any underlying laws - because those outcomes can be scripted. Statistics as a science ceases to work, since statistics is heavily reliant on concepts of probability and independent variables.

In other words super determinism seems to be the belief that the laws of physics themselves are an illusion, and rather than things being the result of other things, we simply perceive them as such because some sort of hidden, probably unknowable internal mechanism predetermined both in advance. So you don't test something and get a result because the laws of physics would determine it, you test something which was predetermined by the universe and get a result which was predetermined by the universe but neither are intrinsically related in any way other than the fact that they have illusion they are due to the spacing in time.

Some Redditor:

In superdeterminism the entire[ty of a] home run event is preencoded in the ball and again in the guy. There is a variable in the ball that says “at time x, you will change direction and fly over the fence”. There is a variable in the guy that says “at time x, you will swing the bat at this angle”. Momentum and velocity are not why the ball flies. This is a well crafted illusion by the universe in superdeterminism. The ball flies for unknowable reasons that strangely approximate the appearance of our laws of physics.
