Umm.. Facebook? Just offering all those features doesn't mean much though, you really have to be dominant in each one, since there's much less moat to debundling consumer apps vs enterprise
Because it would be incredibly convenient. Link a restaurent to your friends in a chat, talk about going there, all of them have the location and you can split the bill, all in the same app.
It might not have the best business index, or the best chat, or the best map, or the best payment manager, but it would be far, far superior to trying to coordinate all of those services through different apps.
And it's not that you need to want all of this, it's that if people around you use it you have enormous pressure to use it as well, because in the previous scenario if you are the guy who doesn't use such app then you have to be catered to specifically through and through, which is annoying for everyone.
If expenditure (hiring) goes up and he's not finding revenue then that's the end sooner rather then later.
it's an interesting vision to be sure, but i'm not sure how buying twitter actually helps it - twitter has already been struggling to expand outside their core product - none of the experiments like moments, spaces, fleets, etc have really taken off. it kind of seems like twitter users just want tweets and nothing else. so now he's taken on a whole bunch of debt to acquire a userbase who is hostile to the app expanding into any other markets? I don't really see a whole lot of evidence that twitter is a good launch platform for an everything-app.
X.com Maps could tie in with Teslas, X.com Carhailing could tie-in with (future) full self-driving; Twitter could be expanded to be more like Telegram + Instagram, with channels, better DMs, "Moments", and more.
There's no attempt to create a single, wide-ranging social media platform, with payments, video, shorts, DMs, and more. China's proven that it can be done. It would create a far bigger moat and network effects, and likely be as successful as Microsoft Teams & 365, a highly integrated solution, are for work.
