Not to be nit picky, but I think you might be wrong about the psychologist part. A core principle, perhaps the most important principle of all, in talk therapy is that of transfer between the patient and the therapist. I don’t think it’s possible to achieve that with a machine, to achieve any real transfer without vulnerability.

A lot of talk therapy today is of questionable quality, in that the therapist or analyst is simply soothing the patient without actually confronting real problems. Machine-based therapy would only exacerbate the problem.

For things like CBT, I’m sure a machine could be helpful. But then again, CBT self-help books already exist.
