I think a better advice would be to learn reading/reviewing an inordinate amount of code, very fast. Also heavy focus on patterns, extremely detailed SDLC processes, TDD, DDD, debugging, QA, security reviews, etc...
Kinda the opposite advice from the blog. :-)
Edit: Somebody pointed out that, in order to read/review code, you have to write it. Very true. It brings a questions of how do you acquire/extend your skills in the age of AI-coding assistance? Not sure I have an answer. Claude Code now has /output-style: Learning, which forces you to write part of the code. That's a good start.
