I don't know that's a good assumption anymore. These students are probably the ones who had zoom from home "school" through formative years, with Chromebooks pushed on them before that. Schools were dropping handwriting from curriculum long before LLM/agentic forms of AI.

Heck, I was graduating high school around the time the first iPhones were coming out and I barely wrote. It was maybe 1-2 essays per school year max, not exactly enough for robust skill development. Exams were almost all multiple choice or 1-2 word short answers at most to make grading more efficient.
