This may be a Haskell thing. But I did try and even for small programs it was cute but not actually an efficiency gain over me just doing it.
Not to mention in real life, I have to deal with fallout and bugs and I think GPT deprives me of key processes that allow me to be excellent in that regard. If you aren't a coder and code a backend with GPT, what do you do when the shit hits the fan?
