The demise of x86 isn't something that can be fiated. It could come about, but there would need to be a very compelling reason to motivate the transition. Technologies that form basic business and infrastructural bedrock don't go away just because of one iteration -- look at Windows Vista for example.
Even if every PC and server chip manufacturer were to eradicate x86 from their product offerings tomorrow, you'd still have over a billion devices in use that run on x86.
It's not the demise of x86. It's the demise of x86 as a moat.
Those are different things. We have seen a minuscule movement on the first, but we've been running towards the second since the 90's, and looks like we are close now.
Windows Vista's problems were relatively easy to solve though. Driver issues naturally sorted themselves out over time, performance became less of an issue as computers got more powerful, and the annoyances with Vista's security model could be solved with some tweaking around the edges. There wasn't much incentive to jump from the Windows ecosystem, as there was no doubt that Microsoft could rectify these issues in the next release of Windows. Indeed, Windows 7 went on to be one the greatest Windows release ever, despite being nothing more than a tweaked version of the much maligned Vista.
Intel's problems are a lot more structural in nature. They lost mobile, they lost the Mac, and we could very well be in the early stages of them losing the server (to Graviton, etc...) and the mobile PC market (if ARM PC chips take off in response to M1). Intel needs to right the ship expeditiously, before ARM gets a foothold and the x86 moat is irreversibly compromised. Thus far, we've seen no indication that they know how to get out of this downward spiral.
This is a terrible example for the reasons stated in the article. Microsoft is already treating windows more and more like a step child everyday - office and azure are the new cool kids
I wasn't trying to refute your comment, nor to imply that you said x86 is on its way out the door, but we are talking about the future of x86 after all.
Intel has already driven its prices downward aggressively [0]. That seems to be part of their strategy to contain AMD while they get their own business firing on all cylinders again, and it's going to be true regardless of whether the majority of the market demands x86 or not. The more that Intel can pressure AMD's gross margin, the more relevant Intel's synergies from being an IDM can become.
Even if every PC and server chip manufacturer were to eradicate x86 from their product offerings tomorrow, you'd still have over a billion devices in use that run on x86.
