This reminds me somewhat of people who aren't particularly skilled at math, or are proud of not being particularly skilled at math.
A common refrain is "I'm hopeless with math/numbers".
And to be frank, calculators exist, so as long as you know how to get to the answer you need... I don't think I have a problem with it.
The author makes his point pretty clear here:
> Not really knowing how to use a computer is deemed acceptable if you're twenty-five or over. It's something that some people are even perversely proud of, but the prevailing wisdom is that all under eighteens are technical wizards, and this is simply not true.
He then offers some suggestions for how to help kids become more technically proficient with computers because he thinks it's a useful skill to have.
