Quite interesting that a lot of comments mentioning the technical side of scaling, when the bulk of the post was about the more social side of things.
While I don’t agree that decentralization itself is a dubious goal, the argument that moderation, the legal side of things, etc… is not scalable (moderation especially in its current form where the entire fediverse can report anything) seems quite true? We can’t rely on generous people hosting instances, taking legal risks and spending time for it if the fediverse wants to grow bigger than what it currently is.
