> He’s simply saying that ChatGPT was able to point them in the right direction after 1 chat exchange, compared to doctors who couldn’t for a long time

He literally wrote that. I asked how he knows it's the right direction.

it must be treatment worked. otherwise it is more or less just a hunch

people go "oh yep that's definitely it" too easily. it is the problem with self diagnosing. And you didn't even notice it happened...

without more info this is not evidence.
