For 99% of the functions I've written in my life? Absolutely drudgery. They're barely algorithms. Just bog-standard data transformation. This is what I love having AI replace.
For the other 1% that actually requires original thought, truly clever optimization, and smart naming to make it literate? Yes, I'll still be doing that by hand, although I'll probably be getting the LLM to help scaffold all the unit tests and check for any subtle bugs or edge cases I may have missed.
The point is, LLMs let me spend more time at the higher level of abstraction that is more productive. It's not taking it away!
