I think XMPP is a really good contender in the non-centralized personal-and-public messaging space. It doesn't look like an insurmountable effort from one person to support the XEPs required to create a competent chat application, unlike my impression of Matrix.
I think a nice, lean-but-glossy desktop client (we already have Conversations on mobile) would be really good for the platform. It's a lot easier to fight network effects if the end-user-experience is tangibly better (and you can do a LOT better than the current incumbents that are Slack and Discord.)
