Meanwhile, my early-teen step-siblings have very similar interests to what I had back in the day (they enjoy playing games like roblox/minecraft on the computer, and FPS on consoles) - but are way less comfortable messing with the OS to troubleshoot vs what I was doing at their age. They were raised with tablets, where things just kind of work. When they do want to learn something, they pretty much always go to youtube first - and I'm not really sure if that's more effective or less effective than what we used to do, or if means they will have a harder time parsing technical docs later on in life.
They've expressed interested in computer science fields, and I do think they'll be able to learn it just fine. In some ways, maybe the exposure to more polished UX will make their bar for those experiences higher than what my generation would accept.
