The most direct application of A.I.s to medical practice is that of surgical robots. Though robots have been assisting surgeons since the 1980s, they’ve been non-autonomous, human-operated tools until very recently. They were just another device for surgeons to use.
Recent developments in machine learning have made it possible for surgical robots to become increasingly autonomous. Again, the technology is still in its early stages, but tests have begun to demonstrate the potential for the robots to be more accurate and precise than humans in the OR. While it’s unlikely that machines will totally replace experienced surgeons in the conceivable future, there’s the definite possibility that they will begin making procedures easier for them.
