If an AI was provably 100% correct then I guarantee you people would listen to it.
People seek for god & other higher powers for much less reasonable logic than "a machine that is always correct no matter what".
The reality is AI as it's known today (generative stochastic models) can not ever reach "100% correct", by definition of being a generative stochastic model. So you're essentially discussing a fantasy computer that we are not close to every having IRL -> It's not relevant.
