Have you tried using chatgpt/etc as a starting point when you're unfamiliar with something? That's where it really excels for me, I can go crazy fast from 0 to ~30 (if we call 60 mvp). For example, the other day I was trying to stream some pcm audio using webaudio and it spit out a mostly functional prototype for me in a few minutes of trying. For me to read through msdn and get to that point would've taken an hour or two, and going from the crappy prototype as a starting point to read up on webaudio let me get an mvp in ~15 mins. I rarely touch frontend web code so for me these tools are super helpful.
On the other hand, I find it just wastes my time in more typical tasks like implementing business logic in a familiar language cause it makes up stdlib apis too often.
This is about the only use case I found it helpful for - saving me time in research, not in coding.
I needed to compare compression ratios of a certain text in a language, and it actually came up with something nice and almost workable. It didn't compile but I forgot why now, I just remember it needing a small tweak. That saved me having to track down the libraries, their APIs, etc.
However, when it comes to actually doing data structures or logic, I find it quicker to just do it myself than to type out what I want to do, and double check its work.
