Not sure if you're kidding or not, but to write great maintable code, you need a lot of understanding that a LLM just doesn't have, like history, business context, company culture etc. Also, I doubt that in it's training data it has a lot of good examples of great maintainable code to pull from.
He isn't kidding. I have a directive to write the shortest, least complicated, readable business code and it makes a huge difference

Neither do most humans writing such code, i have seen llms generate better code than 90% of coders I have seen in the last 20 years
