Man, I didn't realize that article was written in 2013, it could've been written today, and it still would've been true.
I think one of the biggest contributions to the tech illiteracy of people is, 1. Schools don't really teach you about that kind of stuff (in my experience, or unless you take a special course) and 2. Everything is basically done for you now, its incredibly easy to do anything basic on computers.
So when the author says it's the 30-50 year olds that know how to use computers, today it's the 40-60 year olds. I'd say it goes older than that.
One thing that used to bug me on reddit was youngsters going on about how over-50s wouldn't know how to use a computer. That hasn't been the case for decades now.
It's actually the 8-80 year olds that don't know how to use computers.
Most people don't know. They just know how to use a handful of programs. But the vast majority of them don't understand the basic concepts behind them. Things like files and directories are nebulous at best.
Does it matter? A little, because so much stuff revolves around computers nowadays. Which means that they don't really understand the world they're navigating daily. OTOH, they live perfectly well as they are, so it clearly doesn't matter to them.
Hear hear! We 40-50+ year old geeks were learning the Internet as it rolled out. Before that we were upgrading our PCs and modems as funds permitted, joining & running BBS's on DOS. OS/2 seemed futuristic and I ran it for a while, but Linux won my heart. As a teenager, I had my favourite kernel hackers, tested their patches, chatted with them on IRC. Before that, we had our C64s, Amiga 500s and similar. We had the greatest opportunity to learn, and we loved it.
Over the last 10 years I've really had to dumb down my interview questions, covering a wider range of topics until I (hopefully) find a spark of passion and beyond-user-level knowledge about anything (even unrelated to the position)... it used to be easier.
I feel like getting into opensource software is easier than it ever was at least, the biggest Barrie's I see are people thinking they can't and advertising making people defensive about sticking to proprietary options.
I still remember getting in trouble at my public school with the IT admin because my friends and I discovered how to write BAT files, and had the brilliant idea to create a bunch of fork bombs that self-replicated until they froze their host computer.
Unfortunately I think kids today don't even get enough leeway to figure that sort of shit out. But kids are awfully good at finding cracks in systems, so maybe they've just figured out how to get up to similar hijinks with GUIs and cloud storage.
Teaching direct tech through schools is problematic too because by the time they update the cirriculum the reality had changed. Concepts and diagnositcs would be a lot more useful, then let the kids have the tools to find the issues from there
