The parent you replied to said that they could write books which would be useful for instruction if the accuracy problem were solved. You said they would never write anything worth reading because they can't be insightful. What I said was 1) they could write instructional and reference books and no one claimed they were insightful and 2) that they are useful to experts even if they are not insightful. I'm not sure what we are arguing about anymore if you are not going to dispute those two things.
