Open source, open protocol. The superapp is the holy grail of consumer experiences but it's only been achieved in a very insular and siloed manner. The old model was ecosystem based and required large players like apple, Google and Microsoft to build operating systems. One level up WeChat and others have done it as a mobile app. I'd argue we could standardise that model as an open ecosystem but it's going to be damn near impossible to do with that goal upfront. It's more likely some open source niche use case could kick it off but after a decade of wishing, I haven't seen it yet.
