AI guy here.

While it's always important to create a human connection, current technology is getting good at imitating exactly that through conversational systems.

My bet would be on surgery, emergency medicine, and any field that does not readily spew out data for models to be trained and validated; ML is particularly good at unbiased big-picture assessments if the relevant data is available for training and then for diagnosis (and it is not, currently).

I don't think this should be your only concern -- specialities, I hear, differ in lifestyle, and ultimately I think you've got to be interested in your patients and the subject matter.
