I find AI responses to be fatuous, shallow and uncritical. It is uncreative (writes doggerel verse; doddles out prose that sounds like the requested style but only superficially resembles it), it chooses middle ground answers even when asked to do more.
If you need a 6th-grader to write some copy for you, then go ahead. But I'd choose an actual 6th-grader instead. They could use the practice, and they will get better with time.
