The problem is that some % of the time they answer at an 11th grade level, and some % of the time they answer at a 4th grade level, with no way of knowing beforehand.
The only way of knowing is after the fact, when the prompter has the knowledge to discern whether the answer is correct or not.
In which case why are we asking questions we already know the answer of, other than these are toys and fun?
I really wonder what happen when the novelty wears off in a few years, where these things are actually useful.
