I don't remember where I read this idea (because now I'm also in the "build your own keyboard" thing and read a lot about this), but the main take is that when you have fluency in mundane task you focus better in the more intensive ones. in fact you already say this: "I sit with a pen and paper and draw diagrams, or write pesudocode until I have worked out what I am going to do. When I was far less experienced I liked typing a lot and enjoyed programming Java. Now I see that every extra line of code is an extra place that bugs could hide and I prefer more expressive languages and more functional / declarative styles of code" ie: You have optimized typing, using something else! ---- I have tried VIM and Emacs a few times and after some few minutes with them I think "This is stupid. Relearn everything will slow me too much, terminal is too limited, and I'm fast enough with "normal" editors." Being slow a typing on vim/emacs make me appreciate how "fast" I'm with native editors like sublime. Also, I have a MS Ergo Keyboard and building a close clone with the minimal changes that I imagine will close the small things that bother me.
