"I bought those expensive knives. Why doesn't my cooking taste better?"
"I picked up an extraordinary violin once. It sounded awful!"
There's an art here. Managerial genius is recognizing everyone's strengths and weaknesses, and maximizing impact. Coding with AI is no different.
Of course I have to understand the code well enough to have written it. Usually much of the time is spent proposing improvements.
I'm a few months in, learning to code with AI for my math research. After a career as a professor, I'm not sure I could explain to anyone what I'm starting to get right, but I'm working several times more efficiently than I ever could by hand.
Some people will get the hang of this faster than others, and it's bull to think this can be taught.
