OpenAI spends about $700,000 a day, just to keep ChatGPT going. The cost does not include other AI products like GPT-4 and DALL-E2. Right now, it is pulling through only because of Microsoft's $10 billion funding
It works if you ask it for small specific components, the bigger the scope of the request, the less likely it will give you anything worthwhile.
So basically you still need to know what you're doing and how to design a script/program anyway, and you're just using chatgpt to figure out the syntax.
It's a bit of time-saver at times but it's not replacing anyone in the immediate future.
I've tried using it myself and the responses I get, no matter how I phrase them, are too vague in most places to be useful. I have yet to get anything better than what I've found in documentation.
My experience is different, the response I get is not perfect but it's good enough to be a start for any decent dev to refactor and build upon with lesser effort than from scratch. Maybe it depends on what language or framework you're asking for.
