I used to think that too. AI can already do better at screening mammography than a radiologist with a lower miss rate. Given that, insurance rates to cover AI should be even lower than for a radiologist, lawsuits will happen, but with a smaller number of missed cases the number should go down.
Paul Kedrosky had an interesting analogy when the automobile entered the scene. Teamsters (the men who drove teams of horses) benefited from rising salaries, even as new people declined to enter the "dead end" profession. We may well be seeing a similar phenomenon with Radiologists.
Finally, I'd like to point out that rising salaries mean there are greater incentives to find alternative solutions to this rising cost. Given the erratic political situation, I will not be surprised to see a relatively sudden transition to AI interpretation for at least a minority of cases.
