Re : "Only old people are using it, which is interesting because they should know better"
Sorry but bollocks. You're talking about the children of the 60's generation who saw computers invade their lives without them knowing either what they could do (the computers) or what they should do about it (the people).
Everyone I know that talks about computers only talks about the one or two programs they know. Most of the time, it's Outlook and Word, plus maybe this one web site (obviously Facebook).
They don't know computers, they manage to putter around in one or two programs. And as soon as something goes wrong, they're lost like a babe in the woods.
Youngsters fare not much better, actually. The only difference is that they know 10 or more programs, and are much less reluctant at clicking here or there to find something out. Good on them, but they still don't know about computers, they just barely know how to use them.
It's not going to get better, by the way. Tablets and smartphones are placing the computer squarely in the consumer (aka idiot) space, meaning that soon, nobody will know what a backup even is, let alone how to go about doing it.
At that point, I'm no longer telling anyone I'm a programmer. I'll tell them I work in a sewage treatment plant. That should ensure that I never get any questions about my job, or about computers.
