5G is still just a networking technology. Its higher bandwidth and lower latency may open up new use cases.

But that does not make 5G a computing platform. Nor does an operating system dominate a networking technology that sentence just does not make sense. Also lets be realistic even if Chinese companies develop their own mobile operating systems, they will still be Linux or BSD based. No company is going to develop an operating system from scratch, when they can start with something that saves them countless development hours.

5G hardware is already supported by plenty of operating systems. And operating system support is actually not that crucial outside of mobile devices. Because if it is used in a traditional network, then an edge device like a router will handle the connection.

Also APPs don't need to specifically support 5G. They may be able to take advantage of the higher bandwidth and lower latency. But that will not require them to directly program for any specific 5G hardware. Low latency connections are also something that already exists, 5G simply improves those things for mobile applications.

VR does not necessarily need any networking, AR could be different, but I can see how there is more of a need for processing beyond what you would want to do on mobile devices, so being able to offload will help with applications there.

Also the truly important technologies on the backend are going to be in industry applications. And the players can simply set up their own 5G networks. Daimler for example started with that already a while ago.

Especially for these big companies hardware with potential back doors from China is unacceptable.

Honestly with the way you are throwing around buzzwords, you sound like some troll with no understanding of the tech you are writing about.
