I know that varies by region, but schoolchildren are generally taught cursive as a faster way to write. It already requires some memorisation with some glyphs being different from block letters. Why not make an additional step and completely replace it with shorthand, making writing an order of magnitude faster?
Upvoted for disagreement. Cursive should be replaced with typing classes and maybe even also swiping classes. Anything hand-written should be as clear as possible.
