I remember when my parents tried to temper a particularly deep obsession with a specific video game from my youth. My father was very quick to brand it as "not real life", "anti-social" and "worthless".
Needless to say, attempting to ban the game from my life was unsuccessful, even with scorched earth policies like physically cutting internet cables. Meanwhile, I firmly credit my time on this game as the kindling to my career as a developer. A point which (along with making more at 23 than he did at 45) I take great pleasure in reminding my father of whenever the opportunity arises.
Here's to hoping your kid grows up and finds an annoying and creative way to say "I was right, you were wrong, check out this pile of cash I got"
