Yeah, you still need to give an AI's output an editing and review pass, especially if factual accuracy is important. But though some may mock the term "prompt engineering" there really are a bunch of tactics you can use when talking to an AI to get it to do a much better job. The most amusing one I've come across is that some AIs will produce better results if you offer to tip them $100 for a good output, even though there's no way to physically fulfill such a promise. The theory is that the AI's training data tended to have better stuff associated with situations where people paid for it, so when you tell the AI you're willing to pay it'll effectively go "ah, the user is expecting good quality."

You shouldn't have to worry about the really quirky stuff like that unless you're an AI power-user, but a simple request for high-quality output can go a long way. Assuming you want high quality output. You could also ask an AI for a "cheesy low-quality high-school essay riddled with malapropisms" on a subject, for example, and that would be a different sort of deviation from "average."
