We have Matrix now, and although most clients are lacking and it can be laggy, in 5 years it will probably be pretty good. I'm especially excited about their P2P work which sounds like it'll allow account migrations, offline messages to nearby people via bluetooth or LAN, etc.
I switched from primarily using a matrix.org account to using one on a smaller server after the big matrix.org hack a few years back. However, my main server is now incredibly bad. I get messages out of order, it goes offline a lot, etc. I don't want to lose my contact list and history again, so I'm kind of holding out for the option to change homeservers/have multiple/have none. It's also annoying how incredibly few Matrix clients support multiple accounts. I know of Quaternion and Neochat, but that's about it. Every XMPP client I've ever used supports multiple accounts. Dino did from version 0.1.
I still use XMPP and IRC at the same time, but I have most IRL contacts only on Matrix. I think it'd be hard to get them all on XMPP as well, so I'm just enduring.
