I've definitely found this to be the case with writing. ChatGPT gets you a "valid" output, but usually a bland and lame one. I think it's better for editing and brainstorming, or for simple tweaks. Specialized tools like SudoWrite are actually more useful as part of a writing work flow.

Pardon the plug, but I co-wrote a little blog post about this with concrete examples, if it is of interest: https://open.substack.com/pub/storiesbyai/p/chatgpt-for-crea...
