Technically, nothing.

In practice, who do you know that’s using it and doesn’t run Arch, by the way?

My point isn’t that IRC/XMPP aren’t technically capable.

It’s that they’re not designed for non-technical users.

I want corporate social media to die. Mastodon and Piefed are far from killing the beast, but they’ve made the more progress than most projects have seen in a long time.

I want corporate messaging to die. Matrix is far from killing the beast, but for a little while, at least it was trying.

Damn. That sucks. (Edit: Referring to the comments saying Matrix is dead and dying.)

I get that IRC and XMPP are more stable and built around federation from the ground up, but… they’re not Discord replacements.

That was IMHO, the point of Matrix/Element.

Tell me if I’m wrong, but a significant part of a network’s resilience is the number of nodes and users.

Without a glowup or some kind of repackaging, IRC/XMPP are doomed to stay niche.
