If we can all agree that cannabis is bad for the still-developing mind, and can generally get on board with the idea that kids should be kept as far away from it as possible, because it's addicting, because it causes long-term alterations to brain development, because it diminishes motivation and hijacks executive functioning networks, why is it so hard for society to consider treating smartphones, social media, and highly-immersive video games like MMORPG's, with essentially all of the same effects, the same way?
I am part of the generation that grew up with MMORPG's from early childhood (I was about 9 years old when I made my first RuneScape account), but approaching 30, I don't game at all anymore for the exact same reasons I don't touch cannabis anymore. Instagram, Snapchat, TikTok, Facebook, it's all the same thing for teenagers. At a neurological level, these platforms are as highly addicting and neural-network-altering as actual psychoactive pharmaceuticals, legal or otherwise.
Paleolithic emotions, medieval institutions, and god-like technology is a combination that we're not nearly as well-adapted to as we think we are.
