Earlier quoted context omitted.
Medical analysis I don't think I would rely on a description from a Mechanical Turk human for describing what they see in a pictue. Is that a tibia or a fibula?!?
Right - you don't send to Mechanical Turk. You instead send it to a highly trained backend workforce, presumably highly skilled in the vertical that you are doing analysis on. And, it's not just a picture, but video/sound/other sensing. Who knows what the next advances in remote telemetry will be.
Once your workforce is skilled all kinds of new opportunities of this nature open up.
