Should everyone be interested in understanding the basic concepts of computers and the Internet?

I find it sad when I see or hear someone who’s not interested at all in understanding the basic concepts of computers and the Internet. I mean like my Mom, who likes to use her email and her online banking service, but doesn’t want to learn what a “URL” or even a “file” is… I know I can’t ask for everyone to have the same passions as me, but I think in 2009, using a computer and surfing the Internet are probably the activities that are common to the most people. So, what do you think, should everyone devote a little effort in understanding the basic concepts of computers and the Internet?
