Just as an example: both Facebook and Snapchat (and I'm sure others) have tried adding games to their platform. Both efforts have failed because you can get a better gaming experience by playing a standalone game. If you want to play with a friend, you can message them and say "hey, let's play X." There is limited upside to playing in Facebook or Snapchat, and a lot of downsides (limited catalog, performance restrictions, etc.)
One exception to this is any feature that requires exposure to an audience. Social media is very good at exposing people to content. Something like Facebook marketplace can be successful because sellers want their listings to be seen by people and buyers want to go to places that have the most sellers.
The Chinese internet is heavily restricted and censored and regulated by their government. It simply cannot be used as a model in the west. Technology progresses in cycles, and the Chinese and American internet cycles don’t line up. Eg China uses QR codes for payment everywhere because they cycled off cash while the US largely missed that train, but has near universal credit cards and NFC availability. Americans would never pay at a cash register through QR codes.
Android and IOS are great at providing a moldable surface for apps. A super app aggregates censorship to one entity, which isn’t a market force in the west. The “chat bot” style super apps also didn’t take off in the west because our technology is more expensive. We’re richer so we have, on average, higher end devices that can render more AND we can pay to build more feature rich native apps. We aggregate app data at the operating system level (notification center, Google home app, Siri, Uber integration into native mapping app, etc). China can’t because most of android is created in America, and they’d essentially have to hard-fork it to build changes their way (again those changes largely include censorship choke points)
And can Musk and others staff up in China (if US and Chinese politics/government allows it)?

I think you'd have to provide a lot more research to "996 (72hr weeks) apparently works in China". What type of companies, what type of jobs, ubiquity etc.
In order to make 996 work in the US, there would need to be a pretty big oversupply of talent (and a lower standard of living) to make people desperate enough to give up their entire lives to their work. Unfortunately, I think we may be getting close to that about now or at least heading down that path.
Considering the leadership culture that grew twitter to nearly ten thousand, for Twitter, I don't think "dozens" was anywhere near feasible. I suppose it depends on your definition of "product".
