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’m ancient, but I learned both to use the computer and English when I started gaming on the family Amiga at around age 6. My fondest memories were of adventure games like King’s Quest and Space Quest, which incidentally required decent command of English.
There’s tons of more modern and kid-friendly adventure games out there nowadays, but the principle stands.
One of my friends in colombia learned english the same way. Playing video games with a dictionary by his side and lots of pausing was how he described it to me. IMHO the best way to learn a language is doing something you love.
lol
You’re not ancient, friend.
