Haha, you are perfectly right. I totally admit that I'm an amateur with a low level of ML expertise.

One the other hand, ML researchers with a deep knowledge expertise are extremely hard to find, even among statisticians / programmers. I suppose that the people with a real expertise are working on their own startup or in FAANG.

This leads to a situation where the medical research involving ML is largely without interest or full of bias. It is easy to spot in the literature.
