Asking someone who claims to be a doctor of natural medicine the same might yield you more than half unable to answer.
Since there is no 12 year stringent accreditation process for being a software engineer, I'm not sure why this is a good comparison. There are many people who don't know so many basics of CS who have finished degrees, bootcamps, or have been employed in those roles for years.
Doctors simply aren't able to get accreditation or employment with the same ease as software developers.
