Even fewer people in my extended group of friends and family are aware of Linux now than 18 years ago, and that is saying something. The only people who know anything about it are geeks, and we are a minuscule amount of the population.

I think fewer people are aware of underlying software generally. Presumably there are at most four categories for lots of end-users: "PCs", "Apples/Macs", "iPhones", "Androids". (Of course, more people are using Linux in some form or other now than they were 18 years ago, whether they know it or not.)
