Earlier quoted context omitted.
I bet you are right. But, I also think there’s enough leeway in the idea of “using a tool” to not be surprised that somebody doesn’t count a one-off use of notepad. And I think there must exist at least some people who really never used notepad. Nowadays I only assume someone between, like, 30 and 50 will inherently have to have used Windows at some point. Outside that range, you might get graybeards who were around…
Do you really think people younger than 30 won’t be using Windows in school or at home?
What I’ve tried to express is that there’s a small band where not having used it is unusual and surprising, and that isn’t the case anymore. I still think the majority of people have used Windows at least a handful of times but hearing that somebody hasn’t no longer produces a “how could anyone” sort of response.
