Is it too late for doctors to unionize for AI?

Much of the AI sweeping over the highly skilled work force in the coming years is being trained by that workforce, sometime unknowingly.

Is it too late for doctors to unionize such that their training of the AI would result in residuals?

Radiologists in particular, were singled out due to the ease of taking images and the results for training. Should they not have been rewarded?

AI only (currently) pearly from training by others. Who really owns this? The doctors? The hospitals? The patients?

And I can’t believe I’m saying this, but maybe a crypto based DAO is the answer? Or maybe that’s just an implementation detail.
