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.
Most likely the patient is informed by the practitioner about the risks and they can make an informed decision. That is not the case about ChatGPT where openAI will sell it as the next best thing since sliced bread, with a puny little warning below the page. Even worse when you see all the "AI therapy" apps that pop up everywhere, where the user may think that the AI is as-good as a real therapist, but without any of the responsibility for the company in case of issues.
Maybe you are the one in-a-billion who dies from a vaccine, from a disease that unknowably you would never contract or would only contract it in a mild way. The doctors know if they administer it enough times they will absolutely kill someone, but they do it to save the others, although they will pretty much never bluntly put it like that for your consideration.
