Which is a thing that I don't think is feasible. I could be wrong, of course. But I do agree that authenticity is going to be the issue that social platforms will live or die on.
I think the next evolution of "social media" is more likely to be a return to the old-fashioned notion of interacting with people in person.
But none of our personal experiences is a great indicator of what "most people" do.
84% of people aged 18 to 29 use at least one social media site.
the problem is a lack of ability to recognize worthwhile content, a lack of critical consumption. there is also be a problem to find good content among the mass of junk. but that's already a problem now. i have mostly given up. i find new content mostly through HN.
the problem will be that a lot of good content will remain undiscovered.
so let me make this claim in response: the next big social media platform will be the one that will make it easy to discover actually good content as opposed to popular content.
That's what I mean by it not being feasible. Technically, there are many, many ways to make this happen, but they all come with very serious problems that I don't think most people would accept.
On the other hand, people accept things now that just a short time ago were considered outrageous and unacceptable by the majority of people (in the US, anyway). I maintain hope that this descent will stop at some point, and that hope is likely coloring my expectations.
