> Writing by hand is not one motion but a sequence of thousands of tiny micro-movements coordinated with your eyes in real time, where each letter is a different shape that requires the brain to solve a slightly different spatial problem.

> Your fingers, wrist, vision, and the parts of your brain that track position in space are all working together to produce one letter, then the next, then the next.

Typing is super easy to edit. Writing by hand is hard to modify, it forces the brain to think about the entirety of what you want to write about and organize all the thoughts and sentences in your brain first. Think about writing code on a piece of paper vs typing.
