In my experience kids are very tech-savy. I don't think the 4th grader who can't discover homebrew without a system setting for it is going to be able to do much with it once they've got the terminal open.
Kids can only get savvy with exposure. Those lacking certain privileges (like having a computer at home) likely haven’t had any of that exposure.
I was only able to learn BASIC and the DOS command prompt because I was in a multi grade classroom, and an older boy (5th grader) whose mother paid for him to have programming lessons taught me on the classroom computer.
The teacher had no clue about any of that... she only knew I started spending “too much time” on the computer.
