Not sure about this particular odd plan, but his AI engineering team (ignore your view of him personally) is very good, so who knows what they'll achieve.
Also: the major sources of information that are often overused in training AI, like Wikipedia in particular, are already colonized by politicized rewriting of history & reality. Wikipedia is an outright disinformation source at this point; a key case in point is to look at how it took the most a-historical and extreme approach to "trans" name changes, and immediately rewrites even a public figure's past achievements and successes as if they were the other sex the entire time, bringing a total disregard for reality.
