These "outsiders critique AI" articles never include their prompt. If you blindly copy and paste a brick of text into ChatGPT and ask it to "write an ad about this" then you can expect junk.
Don't you think that's exactly what a manager looking to replace human writers with AI is going to do though? If they don't want to pay a copywriter they certainly won't be hiring a "prompt engineer". Most GPT generated articles on the internet look exactly like what they produced here, and that'll be the case as long as getting something halfway decent requires hundreds to thousands of words that boil down to "please make this actually good".
Man, exactly that. I use GPT a lot and I know what to expect in most cases, it won't solve all your problems, it probably will solve a few and not in the first iteration.
