It's ironic that he condescends towards hunt-and-peck typing, while simultaneously, the wiki he links to makes it clear that hunt-and-peck typists are just as proficient as touch-typists.

One study examining 30 subjects, of varying different styles and expertise, has found minimal difference in typing speed between touch typists and self-taught hybrid typists.[3] According to the study, "The number of fingers does not determine typing speed... People using self-taught typing strategies were found to be as fast as trained typists... instead of the number of fingers, there are other factors that predict typing speed... fast typists... keep their hands fixed on one position, instead of moving them over the keyboard, and more consistently use the same finger to type a certain letter." To quote doctoral candidate Anna Feit: "We were surprised to observe that people who took a typing course, performed at similar average speed and accuracy, as those that taught typing to themselves and only used 6 fingers on average"

I personally dislocated my wrist during the same time that I was supposed to learn touch-typing in school. Hence, I never got around to learning it. However, as someone who spent a lot of time in online discussions, I developed my own typing style that was just as efficient. I only use ~4 fingers, and they move all over the place. But my mind has also memorized the keyboard layout perfectly, and I can type all this without ever looking down at the keyboard. According to most online typing tests, I can achieve ~70 WPM this way, which puts me in the same category as a "professional typist". From my casual observation of others, I also seem to make much fewer typing errors as compared to other touch typists, and have never suffered from carpel tunnel or other symptoms, since my hands movements are a lot more dynamic.

Would it be great if I could type at 85 WPM instead of 70? Sure. But I honestly don't think my mind can even work at those speeds, so I'm not sure what benefits I would be getting out of this. Besides, I'd rather spend all that time doing something I enjoy and am passionate about, instead of training myself to crank up my typing speed further.
