I think there's a real space there, and a lot of what e.g. nurses and doctors do is talking to humans, and that won't go away.

But two facts are also true: a) diagnosis itself can be automated. A lot of what goes on between you having an achy belly and you getting diagnosed with x y or z is happening outside of a direct interaction with you - all of that can be augmented with AI. And b), the human interaction part is lacking a great deal in most societies. Homeopathy and a lot of alternative medicine from what I can see has its footing in society simply because they're better at talking to people. AI could also help with that, both in direct communication with humans, but also in simply making a lot of processes a lot cheaper, and maybe e.g. making the required education to become a human facing medicinal professional less of a hurdle. Diagnosis becomes cheaper & easier -> more time to actually talk to patients, and more diagnosises made with higher accuracy.
