Hi Cyrus, I'm unable to talk much about my work at Apple but I am currently developing new ways to leverage Responsible AI methodologies in health sensing applications. At Microsoft Research, I developed domain-specific computational models for bacterial quorum sensing which is how bacteria communicate with each other.
I would say that the current state of AI is pretty advanced with regards to the specific techniques but many of these implementations are not production-level ready or haven't been tested in real-life clinical settings to actually be of any use. Yes, what you described is possible but there still remain many issues with bias in these and other types of applications.
