Both of those have long professional mandatory training which does the evaluation once at the start of their careers, and then subsequent hiring is done on prestige rather than re-evaluation.
Same could've been with CS/Software Engineers, until someone decided that making a quick buck out of bootcamps is more important than profession's integrity.
The phenomenon long predates bootcamps. The microcomputer revolution unleashed a huge number of self-taught programmers on the world in the 80s. Most of the infrastructure was built by people who weren't ""qualified"" to do so; so why would they respect qualifications? Why would those who follow in the footsteps of Bill Gates (Harvard dropout) or John Carmack (UKansas dropout) choose not to dropout when they could build things instead?
