The unmentioned problem here is that people are actively reluctant (this is tested, too) to learn the skills that would let them be more independent. I doubt this is entirely related to the total amount of hours spent at a computer.
In some way, computer literacy seems to be a similar scenario than cars: the homo simplex doesn't want to understand how it works, he/she just wants it to work while enjoying the luxury of not needing to understand it while posting duck faces on Instagram.
Let's face it, computer illiterates understand less, pay more and end up having lower purchasing power. Considering that this is entirely under their control, I find this quite fair (I have different opinions about Seniors, but that's another discussion).
To be honest, I can find only one valid reason for this to be an issue: civil liberties and human rights.
I'm intimately and increasingly concerned by how much civil liberties have been taken from citizens in "developed" countries in the recent years, and I am under the impression that this is the direct effect of computer illiteracy spread across all levels of the population.
Citizens are being asked to vote on laws relying on technological concepts they don't understand, and which end up in striping them from their rights.
That's what computer illiteracy is about and that's what (I think) the article should talk about... :(
