Is this a ChatGPT problem or a family system problem? My child is eight years old and writes significantly better than the writer. Her mom and I value education, reading and writing so we work with her throughout the school year. If an older sibling writes that poorly, I feel there are other things going on than overreliance on technology. I hope she makes it through this because the world is becoming increasingly hostile to people with poor literacy.
