Really enjoyed this, Dan, particularly the footnote on the ? of asynchrony of typing/thinking while writing.
I'd love to instrument this for myself. I type at 110WPM; writing a ~5k word essay (involving original ideas) consistently takes me 5-6hrs, or 13-18WPM.
I probably rewrite most sentences at least once, often two or three times, but that's still far below the 110WPM. I don't think I really can "think while typing." Typing is probably just "dead time"; if so, and if I rewrite ~2x, then I burn 90m "just typing."

And so if I could increase my typing speed from 110WPM to, say, 150WPM, I could reduce that 90m to 50-60m. The whole thing is still taking me circa 5 hours. One thing I notice is that doing this roughly consumes "a day's creative work"—i.e. I can't do *another* thing afterwards.

I agree that typing speed isn’t really a bottleneck, but I have wondered if a slow typing speed can reduce the fluidity (or increase the friction) to a degree that meaningfully affects the output.

Did you do anything specific to train to type at 110 wpm, or is it just years of experience? I measured myself, and I’m at ~60 wpm, so I’m wondering how to improve that

Nothing specific. Did Mario Teaches Typing as a kid and then spent many thousands of hours typing. Probably reached this speed around age 16. But I think proactive exercise could have gotten me there much faster.
