Yeah, certainly. That's why I said "not really" instead of an absolute statement, to leave room for cases like that (and I probably should've been more clear).

Yeah, certainly. That's why I said "not really" instead of an absolute statement, to leave room for cases like that (and I probably should've been more clear). But for the most part input speed isn't the bottleneck that people get stuck at indefinitely. And it's also possible for this to change. With programming, for example, if you lose the use of a hand, you quickly find out typing speed is the new bottleneck.
