They’re not directly comparable topics like that. A doctor definitely needs to know more than a computer scientist. But all of medicine compared to all of computer science is not an easy comparison to accurately make, since they’re both such broad topics - in medicine, everything from psychology to pharmocology to genetic engineering - in computer science, everything from transistors to complex mathematics to artificial intelligence safety. They’re both topics that are impossible for one human to understand in entirety, but society requires doctors to know a lot more of medicine.
