What obstacles are there in various nations to people opting to waive all medical liability in exchange for ultra-cheap access to Watson-based or -like diagnoses and robot-guided physical diagnostics and treatment? If I was indigent or a low socioeconomic participant in a Third World nation, then $0.10 USD visits to an autodoc that also dispenses the suggested curative treatment if I sign a waiver would be awfully attractive. Even a 30% success rate would be an astounding improvement against the status quo in many parts of the world, and many people would take it. And the autodoc software devs would get a constant stream of patient data to improve future versions upon. Not an especially pretty situation to contemplate (cue cries of exploitation of the desperate), but one we likely will have to face as these technologies continue to improve.
