It is terrible for a first draft if you're aiming for something that reads like a human being's actual thoughts. Don't let an LLM think for you and create the first draft of "your" thoughts. At most, if you absolutely must, use it as a spell checker. But write your words yourself.

No one wants to know what ChatGPT thinks. We might want to know what you think... But only if it's actually you doing the thinking.
