Good point. My criteria is bad. Technically speaking, Microsoft Excel's capabilities aren't a proper subset of an average competent human's either. Perhaps, When an average competent human's capabilities within their field are a subset of the AI's (for all fields of interest). is a better criteria. Basically if an AI is going to be a doctor, I want it to at least match the average doctor in capability. What I'm concern about are blind spots that the AI might have that the average human (within their field) doesn't. A jetliner pilot AI is worthless even if it can do fighter jet maneuvers with a jetliner but goes schizo if a bird flew in front of it during landing.
