Ask HN: why dont schools offer a tech class?

There is woodwork, metalwork, home ec, graphics (architecture), and IT. Why isn't there a class for people to learn about technology - setup a computer, setup a WiFi network, use Google, configure a smartphone, build a simple arduino system, install linux.

All this things I learnt from friends, dad, and self taught via the internet.

Most of which none of my friends can do but they never had a problem with laughing at me struggling with metalwork. To be clear I don't see this as some kind of torture, I genuinely think there would be great use to this type of class, most of what we learn outside of schools is from our parents. Many in the world still pay someone or asks a geek for a favor to setup their internet and that seems bizzare.

The added benefit would be people might stop asking me to fix their printer issues because im a computer person (lamen for developer)
