Anonymously without fear of being judged by a human who might be required to report dangerous or illegal situations...

How many more people might be saved if they had to anonymously tell a computer the list of drugs they use regularly?

Or to use the author's example, how many ectopic pregnancies might be resolved when the patient can freely admit they were raped by a family member?

In all of those: how would the transition from diagnosis to treatment look like that doesn't either trip reporting requirements/some disclosure/having access to treatment despite family pressures etc.?

If you think patients more easily release such info to a robot than to a human, I think you are mistaken. Trust is a large part of medicine, and many (most?) laypeople would fear breach of confidentiality. Irrational, yes perhaps but still...
