Reminds me of a company (FTSE100) in the early 2000s that had an internal network IP range that used the same IP range as another company, turned out the person who did the networking originally brought a book and the examples used in that book got taken as verbatim. It all got fixed,eventually, when they moved from Token Ring to full Ethernet.

As for the main article, it makes a causal leap. The fact that these patients were hospitalised after intensive AI use establishes an association; it does not establish that AI caused their psychosis. There is some evidence that chatbot interactions may have reinforced or intensified delusional thinking, but no counterfactual evidence showing what would have happened without AI. By the same reasoning, contact with psychiatrists is strongly associated with receiving a psychosis diagnosis and being admitted to hospital; but that does not mean psychiatrists caused the underlying psychosis. The relevant question is whether AI merely featured in an episode already under way, helped trigger it, or materially worsened it. The evidence cited does not yet distinguish between those possibilities.
