I used to type "semi-competitively" (aka just spending a lot of time on typeracer.com) and could get around 170 WPM if I put enough effort into it. (At least when I was younger. Probably slower now.) 18 WPM would make me feel like a snail. However, I feel fairly confident that within 1 - 3 decades some kind of BCI will let any user surpass the equivalent of 200 - 300 WPM after a bit of training. And hopefully even wi…

Okay, first of all, this is great achievement. But comparing speeds isn't really necessary or even relevant. For a person that literally has no other way to communicate nobody will be complaining the can type 20% slower than a person with a smartphone. The fact they can type at all is important. Now, for the speeds, I type 80wpm/400cpm but what is more important I can also freely think while I do so. I don't even kno…

Most people use their visual cortex to see what they are typing, though. EDIT: I mean, on the screen (and perhaps some on their keyboards).

What's the better measure of typing speed: full words correct with no typos, or full words typos included? A buddy of mine used some timing app for our typing speeds, you had to backspace repeatedly to retype a word if you misspelled it. I argued that is unrealistic, you can just use spell check or just catch the typos during your editing read through.

> What's the better measure of typing speed Full words correct with no typos. If you want to measure this, you're interested in the combination of reading speed and muscle memory while typing. If you're making typos, your muscle memory is not good. Using a spell checker to automatically fix those words... Well, the number is not comparable, then.
