Yeah if you've not used codex/agent tooling yet it's a paradigm shift in the way of working, and once you get it it's very very difficult to go back to the copy-pasta technique.

There's obviously a whole heap of hype to cut through here, but there is real value to be had.

For example yesterday I had a bug where my embedded device was hard crashing when I called reset. We narrowed it down to the tool we used to flash the code.

I downloaded the repository, jumped into codex, explained the symptoms and it found and fixed the bug in less than ten minutes.

There is absolutely no way I'd of been able to achieve that speed of resolution myself.
