Samsung should not give up DEX, is mature and works exceptionally well with applications that are supported (wireless DEX with my samsung tv works great). Knowing Google, they will give up after 5 iterations or updates will be very slow. It is good for the ecosystem, I hope it will become more mainstream.

Dex and Android desktop mode are not a single new thing, but multiple features that partially have been in Android for years, like external screens, resizable windows and the (currently rather limited) external screen drawer.
