Why writing by hand beats typing for thinking and learning

I heard this at university from my professors, and I hated it so much, not just because I hate writing by hand, but because it never had any benefit for me.

In fact, writing by hand prevented me from paying attention, because I was writing nonstop with no pause to think. Instead, I didnt write anything, and got photocopies, improving my learning and grades.

To the extent this is true the act of writing software may benefit from a more tactical user interface than a keyboard... or at a minimum thought process during coding should be at a unit of thought level aided by clean simple syntactic chunks easily understood at a glance ... short focused functions ... composed typed functions comes to mind

As always it depends.

If you want to make connection on concepts, creating a graph is better.

Write by hand if you prefer but store it scanned.

Personally, I don’t write by hand because I can delete, search, navigate, all the things that you can’t do with pen and paper.

Learning maybe, but thinking?

Where are the hoards of 10x programmers who use writing by hand to outsmart us mere typing mortals?
