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 ?
No different than Windows. Kids will use what you put in front of them.
When I was fist getting interested in computers I didn’t want to run DOS, I wanted to play Doom.
