But there is already mandatory gatekeeping of surgeons? They went to medical school for so many years, and they are liable to malpractice if they don't do their job correctly. Engineering is the same. They sign building plans with their names and may be liable for damages caused by gross negligence.

Why shouldn't any self taught "software engineer" be liable for damages they caused due to negligence? If we had to sign off builds of critical components (like a pacemaker to stay with the analogy), there would be way more pushback against malpractice in the development process. Of course not all software projects require that level of rigor, but for medical stuff and I'm sure a lot of other fields, it should be mandatory to have at least one qualified engineer that is ultimately responsible.
