I don't know how to feel about this until it is put in relative terms, if the claims are to be believed then out of 200m users that is a fairly low number, suspiciously low to be exact compared to how badly AI can feed into delusions.

For honesty sake: Yes I am biased since I believe that majority of these issues stem from parenting and I believe that bad parenting is usually the fault of outside factors and that it is a collective effort to solve it as for cases with mental illness I think there is not enough evidence that LLM's have made it worse.
