I do 100% support banning voice mode for school. (Again mostly for the socializing... or anti-socializing aspect.)
As a child, your willingness to question a tool that’s already better then you at most tasks probably isn’t going too high, and if you go through early education without exercising critical thinking… well we can point to cursive reading/writing as an example of a skill that completely disappears from a generation when not practiced enough.
Not "we should keep teaching cursive indefinitely."
