I’m not sure how Twitter is helping in creating WeChat for the rest of the world.
The thing is with both OS and browser is that they are really long term efforts and I am not sure if Elon could pull that of anymore. For sure Elon from 10 years ago could, but not sure if he has the patience anymore. Same with Zuck, I don't think he has the patience for what he is trying to achieve.
News. Media - social and otherwise, payment processing, shipping, messaging.
The restaurant ordering thing is about the only box they don’t check.
Not restaurant, but they started on delivery marketplace items. I guess the former would have eventually happened.

Even disregarding the content moderation speed run, the technical problems for Tesla and Space X are fundamentally about four things: physics, mathematics, materials technology and applied computer science. Mostly predictable. Twitter is like any other large messaging or information distribution system. Chaotic. Unpredictable. Highly adversarial.
Think about it. In a cloud of atoms, you don't get a sizable fraction trying to game the rest of them. Materials technology may be cruel, but at least it's not actively adversarial. Lithium batteries are volatile and can explode, but they don't do so out of malice.
With Twitter, EM is quickly learning that people are not that different from him. Awful. And dealing with them requires skills and knowledge that the best engineering can't cover.
Incidentally, I think EM is also finding new peers. He is on course to wreak about 40B worth of economic damage in a month, which puts him in the Truss-Kwarteng category. Quite an achievement.
I believe the thesis is he thinks it's possible to duplicate WeChat as a ubiquitous everything-app (news, media, social media, payments, ordering in restaurants, shopping, messaging) in the West. Why someone would believe that, I don't know.
I suppose the other thesis is that Twitter was horribly mismanaged and can work on far fewer resources to do more if he runs it like Space X or Tesla. That seems plausible to me though in this case it's beyond me why he thinks the actions he's taken will get him there.
