Android is open source, the Linux kernel it uses is open source. This is why you can build ROMs on your own. The proprietary bits are Google specific additions that are entirely optional. I run for example a completely Google free Android phone.
But again, you don’t look farther than the devices you personally use. Most of the servers that run internet sevices are running on Linux. The top 500 supercomputers have been taken over by Linux 100% since 2017 (Development over Time | TOP500). Small devices like internet routers, TV, fridge, washing maschine. Display systems in the bus, for adds in the public, payment terminals in shops, …
I could go on forever… It has taken over virtually everything and you did not even realize.
No, it will replace all the proprietary inefficient payment rails behind the scenes. You will probably not even notice, except that the proprietary apps you use and now utilize it can suddenly send money instantly to each other or can pay directly in the shop without a “virtual credit card”.
Again, they are only relevant in the Desktop space. They are niche systems when seen overall, and they will sooner or latter also kick the bucket. Even Microsoft has already their own Linux distributions they use for components of their Azure Cloud. You can even run a Linux subsystem on Windows that runs the actual Linux kernel, because they fear they will lose all the developer desktops in companies if they don’t adapt.
Comparisons only go so far. All I’m saying is that today the internet has become the default data transport layer we use, Linux has become the default hardware abstraction layer we use and Bitcoin may become the default value transport layer.
The reason why I think this is the case is because there are the same network effects happening right now, and if that reaches a certain size it becomes basically unstoppable. From that point on you either join the winning team or you are left behind.
There isn’t even a second best around to prevent that from happening. CBDCs are just local and as of now just fascistic wet dreams. Other cryptos are centralized and are still trying to fiddle with on-chain parameters to scale. And none of them has even close to the neutrality Bitcoin has and that is required for this to work.
So I’m pretty confident in my educated guess. I can obviously not predict the future and still be wrong, but my predictions have nothing to do with the fact I have Bitcoin (also I’m not in the red). The moment someone gives me a reasonable argument why my reasoning about this topic is full of shite, I will be out. But if those reasons exist I’m pretty sure I will discover them on my own and not hear them from people like you or other people who yell something from the sidelines I have heard a million times already and is just polemic noise that is not based on any understanding of the topic at hand.
