Some of the smartest people I've worked with over my career were horrible typist. I'm not sure how you'd ever measure this but in my experience this hasn't been the case.

I think it depends what your typing speed target is, probably. Even for someone who's got a lot of experience, I think it's easy to get bottlenecked on typing speed when it's not a specific focus. Speaking from personal experience, I've been programming for 20ish years and up until a couple months ago my typing speed was probably 90WPM. I recently started practicing intentionally and it's now up to an average of 125ish. If I were interviewing someone and their typing speed was like 60WPM as an experienced dev then that might be a little bit of a red flag. But with auto complete and whatnot, I think it's pretty easy to be at a solid 70 - 90 and still be a very solid dev, and what you get after that is mostly leaning on autocompletion less and being able to spit out some of those idioms a bit faster than you could copy/paste or fill out a snippet.

But possibly to your point, what I am is a passionate _thinker_. I'll take pretty much any opportunity to get away from the computer and do things in my head instead because I find that it's generally faster. If I were someone who liked to prototype "on paper" then I might've been a much faster typist long ago.
