> So how can it be remotely plausible that Linux will become a mainstream desktop/laptop OS?
Because of time and inevitable changes happening to everything over time.
Remember when Windows was nothing and everyone was using something else? Remember when macOS was nothing and everyone was using something else? Same thing can happen with Linux, or some other operating system. Sure, might take 10, 50, 100 years, but eventually, Windows and macOS (and probably Linux) will be relics of the past.
