I see advertising for Matrix every single time the chat topic comes up. Having looked at the protocol, it seems massively more inefficient than just using XMPP, which has numerous clients and a lot of features. Can Matrix do anything that XMPP can not?

Note that I have read the claims at http://matrix.org/docs/guides/faq.html#what-is-the-differenc... but critizising the minimal XMPP baseline feature set while claiming that XMPP is not being “well designed for mobile use cases” seems like someone wants to have their cake and eat it too – I have used XMPP over low-bandwith high-latency mobile data connections for years and noticed that XMPP's stream syncronization is a really nice feature for that use case.

For the record, the only person on this thread (afaik) actually affiliated with Matrix is me, and we categorically don't advertise but jump on discussions like this one to try to answer queries and dispel confusion & FUD.

The FAQ entry on XMPP needs to be updated, tbh - XMPP works fine on low bandwidth connections, and is typically lower bandwidth than Matrix (at least when using HTTP/1.1). The "not well designed for mobile use cases" was talking more about push notification support & history synchronisation, both of which XMPP has improved since.
