Discord's ongoing enshittification may create a market opportunity for alternatives in the near future. I'd like to think that Matrix could be a beneficiary of that, but the common-case UX needs to be polished damn well when the time comes if they want to capitalize.
MAS and Next Gen Auth open up the way to things like QR-login (complete with syncing all E2EE state and verification!) which should help enormously with common-case UX.
Eh... Discord's enshittified client is still a hundred times more usable than Element — for all its faults, at least Discord is able to deliver and display messages reliably ("unable to decrypt message", anyone?). And for the more technologically oriented, client mods do a lot to improve the Discord UX.
Element X is supposed to improve things, but it's stuck on Android and iOS for the foreseeable future.
