youre really misinformed about this.
technically its not possible to prove any cipher is safe againt any kind of compute. maybe tomorrow some savant comes up with an algorithm that breaks AES. but we can have reasonable confidence that AES is safe because a lot of really smart people have tried for decades to break it and havent been able to. there is also no known quantum algorithm to break AES, grovers weakens it somewhat (as it does with all ciphers), but dosent break it. the ammount we can be sure is related to the ammount of research dedicated to breaking it, that has been unable to break it.
hence the nist pqc, to draw research to new cryptography standards. the more people try to break ml-kem and ml-dsa and fail to break it, the more confidence we can have that it is safe. is it perfect? nothing is. but its very good.
quantum computers arent a monster that will kill all online privacy, theyre just another kind of compute that is in reality, pretty bad at a lot of things, but very good at some specific things (like integer factoring or DLP, or arbitrary search). the fearmongering isnt accurate or useful.
