Yeah, Matrix is a very, very hard sell. I mean, “normal” people (for lack of a better term) are put off by Mastodon, and Matrix is a hundred times more complicated to join. I’m also not sure what it would look like to use Matrix the way I use Discord. Perhaps there is functionality in Element/Matrix I have never explored since I use it more for messaging and group chat, not for communities with multiple channels like IRC/Discord/Slack.

In any case, Discord is too entrenched to be replaced by something that is merely technically superior, or even more user-friendly. Realistically, you can’t migrate entire communities if they’re bigger than a tight-knit IRL friend group, and even that is hard. That seems to be the only reason X still exists.
