Okay, a bit of seriousness, and this may apply to piano.
Today's typing speeds are much faster, several times faster, than in the past.
This is attributed to two things, one mechanical and one behavioral.
Mechanically, the old typewriters we learned on needed a great deal of force. You had to snap your fingers to get the key to fly up hard enough to press the ribbon on the paper. You couldn't use a lot of arm weight. The muscular force required slowed your speed, few typists realistically did better than about 40, which is silly slow on a computer.
Secondly, and this is thought to be the more important factor, typists learn faster BECAUSE they get instant feedback from the computer screen, and they develop a higher degree of skill. Anybody who isn't typing 80 isn't trying, and most of us can do bursts at 120 or more. It is the reinforcement schedule that improves the performance.
