Is your question whether people learn touch-typing automatically due to kids these days having more experience with computers?
I don't know if that follows. My Dad graduated from a Computer Science program in 1969 and has used a keyboard every day of his life since then, but even so he's only a fair-to-middling typist. 4-finger hunt-and-peck, and may or may not be able to use a keyboard with blank keycaps.
In my case, I was using keyboards since I was 6, and when I took touch-typing in High School, it was really frustrating because I was already a reasonably fast typist, but not a touch-typist at all. So my teacher had to break that all down, get rid of my bad habits, and build me back up. It took the entire year to get my anywhere near the speed that I'd had before.
If I had to guess, I'd say that the best idea is to get kids touch typing from as soon as they are using keyboards, so that bad habits don't have time to form. It used to be that the typing class in high school was the first exposure that anybody had to a keyboard; no more.
