Xmpp has had decades to try and hasn’t succeeded. It’s riddled with issues that make it unworkable.

The question isn’t “If this can work with Matrix why not XMPP?”, the question is “Will Matrix have the same issues as XMPP?”

What's your definition of success? Google and Facebook federating?

[scrollaway]

Federating is one goal but is useless without mainstream adoption.

Success is adoption. Enough users to break the network effect.

Signal is currently a good example of roughly the amount of users you need to start breaking the effect. So that's what success looks like. A very low bar version of it.
