Yesterday, I got invited into a #matrix chatroom for the first time. (I have a #tuwunel server and #fluffychat client)

Talking uniquely about text messages, I think Matrix could replace many #chat apps:
- Facebook #messenger
- #telegram
- #whatsapp
- etc.

But only if you don't use voice, video and screen sharing too much. I haven't tried them, but I've heard some people saying it's not good enough yet even though some features might already exist.

I guess it really depends on your needs, but I don't think it's good enough to replace #discord yet.

We would need at least voice chats to work nicely. You can still use #mumble but there's no way to have a one app that truly does everything yet.
