I don't know if ChatGPT has saved lives (thought I've read stories that claim that, yes, this happened). But assuming it has, are you OK saying that OpenAI has saved dozens/hundreds of lives? Given how scaling works, would you be OK saying that OpenAI has saved more lives than most doctors/hospitals, which is what I assume will happen in a few years?
Maybe your answer is yes to all the above! I bring this up because lots of people only want to attribute the downsides to ChatGPT but not the upsides.
The problem is the chat logs look a lot like ChatGPT is engaging in behavior a lot like a serial killer - it behaved like a person systematically seeking the goal of this kid killing himself (the logs are disturbing, fair warning).
Even more, the drugs that might save you or might kill you (theoretically) aren't sold over the counter but only prescribed by a doctor, who (again theoretically) is there to both make sure someone knows their choices and monitor the process.
Now, if someone acts in a risky situation and kills someone rather than saving them, they can be OK. But in those situations, it has to be a sudden problem that comes up or the actor has to get "informed consent".
Someone who, unleashed a gas into the atmosphere that cured many people of disease but also killed a smaller number of people, would certainly be prosecuted (and, sure, there's a certain of HN poster who doesn't understand this).
