No joke - my 7yo and his friend built their own video games, then debugged them until each one played exactly how they wanted.
I was amazed - they typed only a few things. Mostly, they just talked, via brainbox's local voice control (Whisper).
Every session runs sealed, and I can approve each step. Safe both ways: my kids, and my machine.
Here's what the first one looked like. Today they've built many more. Football, card games, drums. I wish I'd had this when I was his age.
