A few responses:

- Since when have the radiologists ever been worse than AI at reading images?

- AI is doing mechanical tasks for the radiologists, so it stands to reason that this makes radiologist more efficient.

- The radiologist is a liability sponge, so if at all possible it of course makes sense to augment the radiologist with AI rather than to try to do away with them. (This roughly gets at your point about the system being unchangeable.)
