Maybe it's just training and experience, but no AI can replace that no matter how good the algorithm.
How many surgeries do you have under your belt?
What happens if an AI system has 50K that it performed? How does the experience compare then?
Many have made the mistake believing never with technology. You are right it is going to take a while, if for no other reason that, even if the tech appeared tomorrow, it would be years before it was approved. That is one advantage regulated industries have.
Also, keep in mind, when you retire, all your experience goes away. With an AI system, that doesnt happen.
This can get into a really interesting discussion.
