The strict definition of touch typing reminds me of how when I was a kid, my parents would always tell me that there’s a specific way of holding chopsticks. You gotta hold the top one like a pencil, and rest the bottom one between the crook of your fingers and your ring finger, and make sure they’re the same length and the bottom one isn’t moving and you’re just using it as a base to press against.

And then I became an adult and visited China and met actual Chinese immigrants and married a native chopstick holder. And half of them don’t hold chopsticks “the real way”. Somehow it all works out. As long as you can eat a peanut with them, you pass.

As an adult I learned that there’s also a whole lot of prescriptive bullshit that basically nobody pays attention to. The strict definition of touch typing seems like one of those. If you can type without looking at the keys, you can touch type.
