I don't think everyone agrees.
Or is it that you think parents should be teaching this—which guarantees it's only going to be taught to the children of the reasonably well-off?
Welcome to the 21st century, where it's widely beneficial for everyone to know how to use computers at least at a basic level, and skills like "how to use simple Excel formulas" are often enough on their own to get people decent-paying office jobs. Because the people already working there were never taught how to use computers in any systematic way beyond, maybe, "keyboarding classes".
Where many governments require forms of various types to be submitted online, and only put out many kinds of information on their websites.
Where it's nearly a guarantee that people are going to be using social media, no matter how much you try to restrict them, so it's a damn good idea to teach them how to recognize misinformation and other kinds of manipulation (not strictly a computer skill, but definitely related).
I'm not talking about kids. I'm saying those kids will grow up, and once they grow up, they will almost certainly be on social media.
If they are not taught about critical thinking, media literacy, and how to recognize manipulations and misinformation while they are still in school, they will be easy prey for all the various kinds of sharks out there.
Nevertheless promoters don't generally want to get rid of traditional teaching tools. Just add digital tools as part of the learning experience.
And contrary to most popular believe, kids don't want to be all the time with the computers.
