We have. Languages like Lean and Wuffs associate formal correctness proofs to all code. This is impractical to do by hand, but AI can bruteforce it. If a proof exists at all - if the code is ever able to compile and verify - then it proves the code is correct.
Barring underspecification, and bugs in the verifier.
That would be ambitious, since we haven't been able to create those things yet to date.
