What is Science?

Strictly speaking, science is the observation and modeling of those things we can't yet observe or model. Maybe substitute 'understand' for 'model' for a clearer picture of what science does -- although most scientists would be careful to use such vague wording.

Applying a technology (e.g., AI) to second guess clinical diagnostics is technology, not science. Science would enter the picture if something unexpected would be learned from such a system. But that is not the goal of AI in most cases. In a clinical setting, the goal is to systematically exploit our knowledge of "this image shows cancerous tissue, that image does not".

The boundary between science and technology can be fuzzy sometimes -- new technology is often required to make new observations. But you can quite clearly distinguish the two if you look at the motivation of the researcher / engineer, or at the results (in hindsight ;).
