What could be the best way to introduce the world of computers to a kid, let’s say of 6 years old, so that he learns to handle it like a toy and stops dreading it like some esoteric, arcane and recondite machine from some eldritch, enigmatic, cryptic and phantasmal world ?


I installed gcompris for my 5 year old. FOSS childrens educational software and games from KDE.
I also bought her a cheap, pink, 65% keyboard and mouse set that make it “her computer”.
There’s also a few free resources to teach typing once your kid can read and write enough to understand what they’re typing. I’ve heard good things about Typing.com and typingclub.com but we’re not ready to start typing yet so I haven’t used them.
Also, if my kids ask a question that’s a little tricky to explain I’ll show them how I use a computer (or phone) to look for answers. One of the few practical applications I’ve ever found for AI is “can you explain [abstract concept] in a way that a 5 year old can understand”. This isn’t explicitly teaching computer skills, but showing them a practical use case and how to dig into their curiosity.
