Which is only needed at the end of secondary school, and only at higher levels. Before that, essays are very short, and should be handwritten, or they not even part of the curriculum.
If we want schools to reflect useful skills, we'd be better off introducing typing and computer skills younger and dropping the requirement for cursive penmanship.
This has already been done (in many cases, 15+ years ago) at most American grade schools -- touch-typing and computer skills instruction now starts only 1 or 2 years after handwriting instruction. This means it is introduced in 2nd or 3rd grade. (Most essay-writing remains on paper until 6th grade, though)
