As someone who appreciates the design goals of both but is a user of neither Matrix nor XMPP for practical reasons (I don't know anyone who is), seeing users of both of these small networks sighing at each other leaves me nonplussed.

An end-to-end solution for interop between the two ought to be insanely high on the priority list. By this I mean it should be braindead obvious if I want to try one of them how to chat with a user of the other. Obviously this is bigger than just the protocol but so what, it's the problem that needs to be solved.

I can't even imagine how working together would not be top of everyone's mind in this space, since chat is all about network effects. The incentives to cooperate are huge.
