The fact that the UK demonstrably reduced suicide rates as a result of making it
very marginally less easy to get a no-prescription-needed painkiller, makes me think that there's plenty of people on the edge.
Easy access to firearms is totally in the same category as easy access to painkillers to overdose on, and has been demonstrated by similar research: https://pmc.ncbi.nlm.nih.gov/articles/PMC4566524/#:~:text=Fi....
I have opined before that I would be surprised if ChatGPT specifically has caused the deaths of fewer than 200 people, just by giving bad advice — that's one in a million of the users, and I think that's plausible given the story of a different chatbot almost leading to botulism poisoning.
I also think that the general internet should have an 18 rating: to the extent that the argument for film classifications is valid, and that the internet is too big to be classified and also definitely contains examples of things beyond the most extreme allowed in cinema etc., we should treat it like it's 18-only content except where demonstrably suitable for younger audiences.
