I love nearly everything about this video, including the passion this guy has for pencils and keyboards, but mostly I loved this quote about typing.
“It unlocks the iterative joy of writing. The ability to race along — to sketch an idea — to go back and change it, to move back and forth. That’s what helps you as you try to get an idea out.”
The idea that you should move back and forth between the tools you use for various circumstances — handwriting for consumption and keyboards and computers for production — is excellent.
