> If we rewound to ~2010, froze Facebook at its then-current feature set, and had Instagram (2012), WhatsApp (2014), Oculus (2014), and the myriad of other aquhires still in existence as independent companies, society would be a better place

Sure, I can see that.

And if Facebook the product went away, society would IMO be in a worse place (until it's replaced :), because Facebook the product is delivering value every day
