Here’s a fun fact: “Doctor” was an academic degree. It was originally meant for theology, but expanded as the scope of academia expanded and natural philosophy became the sciences. We still call the degree “Doctor of Philosophy” as a result of that. Being a doctor of something meant that you were qualified to conduct research and teach at the university level. It eventually meant that you have made a contribution to your field - your dissertation - and the expectation was that you had and would continue to publish research papers in scientific journals.

The idea of a “medical doctor” was a new addition. MDs don’t do research, didn’t do a dissertation, and in general are not equipped to teach and advance the academic understanding of their field.

So I agree. Scientists should get the blue shirts, physicians and surgeons should just wear scrubs.
