If you feed that information into a human brain enough times and from enough sources, they will absolutely believe it too. Humans believe all sorts of dumb things that are objectively false. I don’t think your argument refutes OP.

Once AI has other sensory inputs from the real world, it’s intelligence is basically equal to that of biological creatures. The difference is that right now it can’t see, hear, or touch. Once it’s receiving and incorporating those inputs, as well as way more raw data than a human can process, not only will it be intelligent, it will be orders of magnitude more intelligent than the smartest human in history.
