Yeah, I guess it would be cool to do an X-ray or CT scan of every patient, preferably in repeatable and controlled conditions similar to the AI training set. On the other hand there supposedly were very good results with training dogs to identify covid patients by smell alone. Which sounds faster, cheaper and probably even less error prone (judging by this article). I guess it doesn't scale well and there's not much money to be made, so there's that.

I think it may be the case with AI researchers where if the only tool you have is a hammer then every problem starts looking like a nail /jk
