Yes, agree. I mean GPT-4 is an all in all a fantastic tool, but it's especially good for developing. The moment you transform a blurry idea into structured data in any form (and it helps a lot with that: you can chat like two decent citizens and ask it to transform it to json at any given time), you can pretty much generate infinite boilerplate that's consistent through a whole application: interfaces > tables > migrations > models > forms > tests. But it goes way beyond crud, and during that iterative process you can come up with some sophisticated enhancement that you wouldn't have even entertained and all of a sudden it's easy to implement. It's great for longform code & structure generating conversations and it's great for picking up little details that would have taken the most of the afternoon. I'm in awe, really (as is everybody else?).
And yes, it does make mistakes, very rarely, and you can't really upload the whole source code everytime you want to talk with it, but it makes the programming dream real again (if only for a couple years lol): is not like you don't _type_; there's so many things you stop thinking about. And you can say: oh, there's the catch, but the truth is my own buffer is so much freer all the time, I get to tweak files, with excitement, that a couple months ago would have been very tedious to get a grasp of.
And about code quality: its Elixir is alright, its Typescript is excellent, but it's absolutely flawless at concatenating unix commands: it has read all the man pages. I've aliased more custom commands these couple weeks than in the whole of last year, and my workflow is getting tighter and tighter each day. There's just so much power into this thing.
