AI does what its programmed to do. It does not learn. It simply uses more data. Nowadays any piece of code is called AI to sell it. But AI is nothing more than code being programmed on faster and bigger computers with more and more data and connectivity. But in the end it does what it was programmed to do. And its limited by the quality and breadth of its data.
The other possibility is that the programmers are modifying the weights on data so that information that comes from .gov sites is weighted higher making EPA, DOE, and CDC lies percolate to the top.
