Tech Self sufficiency? On the hardware level, it will take a while. In the software level, I don't think it will ever happen. Yes, the desktop and software suite they use, and the distro they're packaged in are Chinese, But....
the Linux Kernel, the GNU stuff, the systemd stuff, the Freedesktop specifications, Xorg if they still use it, wayland protocols and wlroots, are all developed by people from The West, so if they really want independence, I want to see them replicating all that work from millions of people across the last 30-40 years.
