I liked the response overall, the only thing I find strange is the importance of training new devs. I was never trained, depending on what you consider training to be. Perhaps my homeschooled education, which was mostly being handed textbooks and told to learn what's inside from my hands off mother, shaped my approach to learning. If you have the curiosity, interest, and will power to do programming, you will be successful, however suboptimal or inefficient your approach to learning is.

An issue I see with junior devs is their unwillingness to dig in and stay in the weeds of some hard shit to figure out. To me, that's where the learning happens and current LLMs aren't going to figure it out for you. If you keep at it, you're going to build those synaptic connections in your brain, which makes figuring things out easier over time.
