A lot of people worry that commercial networks joining the fediverse will inevitably take over the network, "like Gmail took over email."
Except, y'know, Gmail hasn't taken over email.
There are 4.5B active email users (Radicati), 1.5B Gmail users (CNBC). About 1/3.
Maybe all the people you know use Gmail.
Maybe that says more about the people you know than about the state of the email network.
Email remains robust, decentralized and diverse in 2023.
@evan I think more folks are drawing parallels to RSS being dropped or XMPP being embraced and then dropped. Sure, both of those technologies are still useful and in active use, but they never recovered their ubiquity after they were dropped from common usage.
And I'd argue that email is waning for folks that haven't taken control of their inbox, but that's a separate, very long rant (erm, "discussion" :) )
