This will only work until somebody figures out how to connect an AI to the typewriter which will have some sort of MIC, and the person will start dictating into it with AI-assisted revisions. Once the dictation is over, the AI-enabled typewriter will be instructed to type the work out.
Testing and instruction should be modified to account for AI. If a student uses an Agentic AI for work, learning, research, then when test time comes, the student should be required to stand in the front of the class and teach the class what they have learned, i.e. "Teach Back" all they learned to the entire class student body and teacher. The entire class, instructor included, will also be required to participate in a Q&A session to make sure that student's learning is not just made up of memorization, e.g. restate the information learned but using different words, different scenarios, etc.
