computer literacy vs. digital natives
The interesting thing about technology is that early adopters tend to be very technical people. The average person who owned a computer in 1982 was probably educated and very interested in technology. A Popular Mechanics reader, if you will. Later, there is nothing remarkable about computer owners. Scientific literacy is not a precondition for computer use.
That leads me to a distinction: computer literacy vs. digital natives. The computer literate is someone who is steeped in the ways of computing. Not a professional engineer, but they approach a computer the way some people approach a car. It’s a machine, you can take it apart, make it do things, and so forth. The digital native is some who is comfortable with computers because they grew up around them. They are consumers of computers, not builders. They know how to use computer, but they can’t really write code or otherwise command a computer. This isn’t necessarily a bad thing. It should be expected that when a technology is well diffused that it is easy to use and requires little training or knowledge.
