My guess at the real reason for the government stepping in to AI regulation is about the coordination of information proving popular narratives false. Once you can consolidate this much information, and have AI that can provide computational models with said data, in an unbiased manor, one can assume lies can easily be countered using real factual data. One can no longer lie if anyone can fact check any information, with unbiased data, formed in such a way that there can be only one logical outcome.
