I specifically said “on the mobile side” after Qualcomm there.
But, since you mention it, Windows 10 will soon run on Qualcomm chips, with x86 apps running in emulated instances.
Qualcomm this year is directly competing with Intel (and others) in the server chip market where ARM is actually quite viable. Microsoft even ported Windows Server to Qualcomm’s platform.
Lets be clear here: Microsoft and Apple are both hedging against Intel. The work they’re doing (in Microsoft’s case, decouple Windows from x86 dependency, in Apple’s case, to basically buy all the best semi talent in the world) isn’t like, just for fun.
As for why I would mention mobile in the first place? Because it dwarfs the desktop market, has done for awhile, Intel knew it, and they couldn’t compete. That’s why. The mobile chip designers are moving up, and Intel has already failed to move down. And this, in a year where Apple has sold millions of devices with silicon spun with a more advanced process than Intel currently has. That’s never happened before, ever.
