It really depends on the situation. Can I write maintainable code? Yes, to the extent that the average senior dev can.

But that isn’t the same as being afforded the chance to write maintainable code. I’ve been part of teams where the timeline is so tight that technical debt is just a thing that builds up to be dealt with “later” and more stress is put on getting things done instead of keeping things maintainable.

The fact of the matter is that humans can while LLMs currently can’t.

On top of that, a human dev is going to be able to understand context a hell of a lot easier if they’ve previously worked on it, even if the code is less maintainable.
