As someone who works in a related field, I think Hinton's original assessment is mostly correct (although we will always need a few radiologists around).
However, the timelines are far too optimistic. It takes time to refine the technology for day to day use, adapt mindsets and processes, and update regulations as needed. But it will come, it just needs more time.
It's the same story as self-driving vehicles or programming. AI will have an impact. It just takes time.
