Centralized services are usually more efficient than decentralized but that’s not the primary goal of the fediverse
My main concern with this is, if only a handful of centralized social network reached long term stability, and most of them are unprofitable, how can Lemmy (or any other foss fediverse project) completely hold itself on 2 unpaid developers and immense unpaid work from volunteers in the long run.
Because ok, Lemmy.world is looking for experienced sysadmin and that post already had a little backslash, but this isn’t sustainable long term, it’s impossibile to keep scaling like that.
And I feel that’s one of the biggest reasons holding back the fediverse
