Earlier quoted context omitted.
I don't know what steps they can take. I suppose the best course of action is to deactivate the account if the LLM deems the user mentally unwell. Although that is just additional guardrails that could hurt the quality of the LLM.
At some point they have to say "if we can't make this safe we can't do it at all". LLMs are great for some things, but if they will do this type of thing even once then they are not worth the gains and should be shutdown.
If they're going to curtail LLMs there'd need to be some actual evidence and even then it would be hard to justify winding them back given the incredible upsides LLMs offer. It'd probably end up like cars where there is a certain number of deaths that just need to be tolerated.
