I used to write code by hand.

AI has removed some of the tedium, and freed up more of my bandwidth to think about the problems I’m trying to solve and what the actual best ways to solve those problems are.

Only once I have a good feel for the problem I am solving do I go to the AI for help implementing.

My style of prompting usually leads to code that is very close to what I would have manually typed. I review it and tweak it until it is effectively identical to what I would have typed.

The speed up is significant. YMMV.
