My sons are in that age bracket and when they requested a laptops for themselves (older sister got one for school stuff) I "borrowed" decommissioned thinkpads from work, threw empty ssd's on them and gave computers to boys with linux mint installer on usb-stick. Younger one got it running in couple of hours without any help and is actively learning on how to use the thing, yesterday he told me how he had learned to open software using keyboard shortcuts and in general is interested about the tinkering aspect of things. Older one has a bit more pragmatic approach, he got the installation done as well but he's not interested about the computer itself as it's just a tool to listen to a music, look up for tutorials for his other interests and things like that.

Both cases are of course equally valid and I'm just happy that they are willing to learn things beyond just pushing the buttons. But I'm also (secretly) happy that my youngest shares my interests and he's been doing simple games with scratch and in general shows interest on how the computers, networking and other stuff actually works.
