I get that impression too - but also it's HN and enthusiastic early adoption is unsurprising.

My concern, and the reason I would not use it myself, is the alto frequent skirting of externalities. For every person who says "I can think for myself and therefore understand if GPT is lying to me," there are ten others who will take it as gospel.

The worry I have isn't that people are misled - this happens all the time especially in alternative and contrarian circles (anti-vaxx, homeopathy, etc.) - it's the impact it has on medical professionals who are already overworked who will have to deal with people's commitment to an LLM-based diagnosis.

The patient who blindly trusts what GPT says is going to be the patient who argues tooth and nail with their doctor about GPT being an expert, because they're not power users who understand the technical underpinnings of an LLM.

Of course, my angle completely ignores the disruption angle - tech and insurance working hand in hand to undercut regulation, before it eventually pulls the rug.
