"It's no longer necessary to be a computer person in order to use a computer, and that means lots of people are using computers who aren't computer people!" TRAGEDY! Lots of people use cars and don't know how to fix them. Lots of people live in houses but hire people to repair the plumbing or the electricals when those things break. You don't have to completely understand something to use something, and that's OKAY.
But let me turn the argument 90deg: would you say the same thing about math or about reading? Yes, people DO live life without learning arithmetic or how to read, but they probably also have a higher likelihood of poor outcomes in life.
I think the argument being made is that, because computers are so vital to our existence today, fostering computer hacking as a skill and having a real understanding of the computer is a fundamental that must be taught for society to keep advancing.
The snark of the article muddies the waters, but I tend to agree with the sentiment. IMO, having kids get a deep understanding of computers and making scores more tinkerers/hackers is more important than teaching the next generation to drive cars.
