I wholeheartedly disagree. Apple is probably the "first, best" case of ARM, but there's absolutely nothing stopping anyone from making a similar investment in ARM hardware. Indeed, Amazon is already doing so with Graviton, and we're seeing similar improvements in both raw speed and in perf/watt like what we're seeing with M1 chips vs. Intel[0]. And that's one of the best parts of ARM -- the design itself is available for licensing, unlike x86, so anyone can pony up the cash and build up their own customized chips that maintain compatibility with base ARM code (maybe needing a recompile to take advantage of new hardware features).
