Today, I was listening to the Lex Fridman podcast with John Carmack. It reminded me that John Carmack does not have a university degree, yet, he is one our generation's globally recognized masters of software optimisation. There are few in the world who can do what he does, and he has no uni degree, nor (I assume!) any "national certifications". Michael Abrash is similar.
On a personal note: (US) Wall Street has similarly ineffective gatekeeping with the Series 7 & 63 exams: My father called it "toilet bowl knowledge" when I studied for it. He said: "Once you are finished the exam, you can flush away that knowledge. You will never use it again." He is right about more than 90% of the "knowledge" required to pass those exams.
