In my experience it Just Works ™️. I spin up a distro/toolbox, compile some software (e.g. Emacs) then run the executable inside the container, and up pops the GUI window.
If you use distrobox, you can even distrobox-export
desktop files, at which point a containerised gui application is practically indistinguishable from one installed on the host system
Please somebody correct me if I'm wrong, but I really don't find the "chip makers don't have to pay licence fees" a compelling argument that RISC-V is good for the consumer. Theres only a few foundries capable of making CPUs, and the desktop market seems incredibly hard to break into.
I imagine it's likely that the cost of ISA licencing isn't what's holding back competition in the CPU space, but rather its a good old fashioned duopoly combined with a generally high cost of entry.
Of course, more options is better IMO, and the Linux community's focus on FOSS should make hopping architectures much easier than on Windows or MacOS. But I'd be surprised if we see a laptop/desktop CPU based on RISC-V competing with current options anytime soon.
