It is not so easy. First, AI is as biased as its training dataset, and frankly, MSM media and the arts today are already gone. To be better than MSM, it would need a curated training dataset focusing away from the mainstream internet and into books and classical stuff - there are people working on that, but it will be labelled as 'right-wing-nazi-everythingfobic". Leftists will only use even leftier AI.

Second, AI hallucinates by its nature, and a child can not see it. Unsupervised children with AI (even honest and unbiased) would be very dangerous, children would randomly learn totally untrue things, about any subject. The most creative children, who think out of the box and mix contexts, would see hallucinations even more often than others.
