I'm very happy I attended an optional touch type class in high-school (on typewriters, actually). My recommendation for kids would probably be to learn to touch type, on a better layout (eg dvorak, colemak, workman).
Either way, proper touch typing is more than typing fast, it's also about "sustainable typing": posture, strain, reducing rsi - as well as being free to copy (read text to type in, not having to look at the keyboard or the screen where typed text is displayed).
I've not met many people that proper touch type, even programmers. Even if being able to copy a page of example code from a magazine/book is a useful skill.
