They rightly pan Horizon Worlds as it's presented now as disturbingly reminiscent of the empty-but-not-insignificant hype around Second Life. And of course the utopian attitude of tech bros is a meme ("Making a difference; making the world a better place... through minimal message oriented transport layers.").

But Facebook really did make the world better... at first. And if they wanted to they could go significantly farther and make the world better, by just doing what they do now, but cut back the design in which anything productive that someone wants to do on there is through a clutter of garbage that's worse than the worst targeted ads from faceless corporations -- that which reinforces addictive behavior. Instead, look at Facebook's special-purpose competitors -- take Meetup and Google Groups for irl socializing and networking, something that could be done for free on Facebook, but that many are avoiding because of that ickiness. Company feeds on Twittertagram are duplicated on Facebook, so there's no reason why I should be able to view people's Twitter posts without logging in while Instagram and Facebook are locked. If the original idealism was that more access + more communication + more socialization (irl and virtual) generally grows your userbase while also improving society, then just in terms of how they've shifted the design of their core product, they've been working against that.
