It's starting to replace some low-level jobs, like copywriting and art-based positions. For development, the only thing I've found it good for is giving me example usage for custom Apis and other things that I can't just Google/download.
It's marginally better than Stackoverflow (which I've only ever used to give me an idea that I then turn into my own code, usually written from scratch, because most code is littered with security vulnerabilities).
It's a long way from replacing developers or increasing productivity on a measurable level. It's also like building your business on quick sand. Some feature you use today might be put behind a higher pay-tier (or removed) at any time.
