> We burnt huge amounts of time on E2EE (which turns out to be really hard in a decentralised world).
For whatever it's worth, I think Matrix's approach to E2EE and investment into trying to solve some of the really hard problems in that space was completely worthwhile, even though it's painful and even though it set Matrix back in other ways. It's the type of fundamental problem that would be hanging over Matrix indefinitely until all of that time was devoted to it, and I think doing it early was the right move.
My feeling is that what Matrix demonstrated was that decentralized E2EE is itself a giant UX problem (both for users and in some ways for developers who are building clients as well), and that solving it requires a ton of UX iteration and thoughtful iteration on how to share/encode keys, handle sessions, respond to unencrypted sessions, etc, etc... That is something that a lot of other platforms haven't really grappled with, and I think ignoring that problem would have risked imposing a hard limit on how effectively Matrix could roll out E2EE by default without it just staying as a really annoying option that most people avoided.
That being said, I do agree with the rest of your comment. I've noticed some faster improvement on UX lately from Element, and it's been getting steadily better (I love the direction spaces are going), but it's still not quite over the line for me.
I'm just not sure... I don't know that I would phrase that core work that's been happening as if it was the wrong focus, I think that stuff just takes a long time to build and the benefits aren't always immediately obvious to users, or that it takes a while to start paying out those benefits. A good E2EE UX isn't really about impressing users, it's more about being invisible, which can be frustrating because getting it right just means people complaining about it less, it doesn't mean having an advertisable feature. But it's still important though if you want people to actually use E2EE.
I am still excited about P2P chat, about taking server moderation seriously, etc... That all has a ton of potential that could pay out in really significant ways in the future, even if it's not user-facing right now. I don't think any of that is wasted effort or that it's not important. But I'm also happy that Matrix/Element is focusing more on general user-facing UX now, and I do agree that there's a lot of iteration and improvement to be done there.
