It's also just patently false to call QM settled science at all. Non-locality was NOT resolved by the Bell's theorem experiments. Superposition is still nonsense. Einstein and Schrodinger were not wrong. Bohr did not "win" the debate. There has been nothing but obscurantism and verbal tapdancing around the problem. The Copenhagen interpretation declared victory, wrote nonsense into all the textbooks and told everyone that they just weren't smart enough to understand it and if they wanted a career they better "shut up and calculate". Sound familiar? That's how we ended up building on sand and ignoring the fact that the best minds in physics in hundreds of years plainly and simply showed that QM as we know it is a broken theory that needs to be replaced with something that actually solves nonlocality. (And not by resorting to "many words" hogwash). QM is not even close to being settled the way that Newtonian physics and relativity are. It's a jumble of quasi-mystical jive maintained by social fear. And the PQ migration push is a motivated social attack on cryptography, based on an unfalsifiable, nonsensical threat, based on physics that are known to be broken. "Reality isn't real and things are nonlocal, which, ignore the contradictions and nonsense terms, it's true despite nothing being real and you can't ever measure it but trust me bro, you're just not smart enough to understand it." This is fiat science. It's true because we say so and you will get punished if you question it. Now shut up and calculate. And take your vax, pleb. You're not a virologist! No. Don't trust, verify.
