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 ?


Maybe my https://fabien.benetou.fr/Content/BuildingAComputer could help.
I also answered your question in https://lemmy.ml/post/38363131/21987482 but it’s intertwined.
I wouldn’t “teach” them what a computer is, I would co-explore with them instead.
