In 2018, the W3C validated a protocol called ActivityPub that allowed interoperability between different social networks.

Instead of one social media node acting as a centralizing silo, each of them can federate -- cooperating to send messages across the universe that is the network.

The Fediverse.

This is social media's version of the United Federation of Planets.

It is ARPANET yet again -- a model that continues to work over decades.

And it's the future of social media.
