It’s time to admit quantum theory has reached a dead end
Amusing to see all the pessimistic comments form programmers who have zero understanding beyond high school maths thinking somehow there is a magic solution to all the problems in physics like you can just refactor everything.Quantum field theory is definitely not stuck in the 1920s. Modern physics has a lot more going on than 19th century mathematics. We understand quite a lot about the mathematical structure underpinning quantum field theories.Quantisation is a nearly well  understood process, it’s not simply heuristics and guesswork.Unfortunately, it’s not like much smarter than anyone posting here haven’t considered lots of wild ideas, it’s just that a lot of them haven’t worked, and we have been funnelled into what we currently have. There are infinitely many more interesting mathematical objects and ideas possible than what is allowed.Quantum mechanics, or say quantum field theory, has really good predictive power. What ever comes next needs to at least be consistent. Unfortunately I think things are going to get more complicated. Don’t use your intuition developed from grinding out web crap to try and reason about the forefront of human knowledge.
