I’ve worked medical software packages, specifically a drug interaction checker for hospitals. The system cannot be written like a social media website… it has to fail by default, and only succeed when an exact correct solution was determined. This result must be repeatable given the same inputs. The consequence is people die.
Similarly the non-determinism in ChatGPT should be handled at a higher level. It can suggest possibilities for diagnosis and treatment, but you should still evaluate those possibilities with the help of a trained physician.
a diagnostic system should not necessarily be deterministic, because it always operates on incomplete data and it necessarily produces estimates of probability as an output
Humans are probabilistic systems?! You might want to inform the world's top neuroscientists and philosophers to down tools. They were STILL trying to figure this out but you've already solved it! Well done.
