I use it all the time, it's significantly improved my productivity.
It's a little like pair programming with an incredibly eager junior developer who has read a lot of the documentation of every popular API in the world. I need to review the code it produces, but it's very fast, and its suggestions are usually great.
It's annoying when I know exactly what I want to write, and most helpful when I'm unsure (either because I'm trying things out, or if I'm using a new API or a language I'm rusty at).
This seems like a Google problem. Google was really helpful when it had a tonne of organic content that it could systematically steal from, plagiarise, and rip off to the point of devaluing the entire internet. The result with google was absolute centralization of that content and therefore a withering of the organic content. I wonder if we're going to see the same thing with these AI tools. It's fine to learn from 100,000 developers all writing code. But if you steal their IP, rip off their designs and plagiarise their work to build your tool what you end up with is a tool that is basically just learning from itself. No one really writes basic code anymore, but as a result there's no source for the AI to learn from. In other words, it centralizes knowledge but doesn't advance knowledge, and in the process it devlues anyone else advancing knowledge.
