kinda funny that Microsoft has tried and failed multiple times to make Windows on ARM work

and then valve is probably going to succeed, to Microsoft's detriment

I think the problem is that, until recently, there was little impetus to actually run Windows on devices where ARM actually has a meaningful advantage over x86. The Windows ARM laptops out there today don't impress, not just because of the software, but because the hardware itself isn't "better enough" than Intel or AMD to justify the transition for most people the way Apple Silicon was, especially for games. That is to say nothing of desktops, where battery life isn't even a concern.

Valve is using ARM to run Windows games on "ultra portable" devices, starting with the Steam Frame. At least right now, there isn't a competitive x86 chip that fits this use case. It also feels like more of an experiment, as Valve themselves are setting the expectation that this is a "streaming first" headset for running games on your desktop, and they've even said not to expect a great experience playing Half-Life: Alyx locally (a nearly 7 year old title).

It will be interesting to see if Intel/AMD catch up to ARM on efficiency in time to keep handhelds like the Steam Deck and ROG Ally from jumping ship. Right now it seems Valve is hedging their bets.

I don't think there will ever be a competitive x86 chip. ARM is eating the world piece by piece. The only reason the Steam Deck is running x86 is because it's not performant enough with two translations (Windows to Linux, x86 to ARM). Valve is very wisely starting the switch with a VR headset, a far less popular device than its already niche Steam Deck. The next Steam Deck might already switch to ARM looking at what they announced last week.

x86 is on the way out. Not in two years, perhaps not in ten years. But there will come a time where the economics no longer make sense and no one can afford to develop competitive chips for the server+gamers market alone. Then x86 is truly dead.

My problem with this take is that it takes ARM > x86 as some kind of given, like there is an inherent flaw with the x6-64 ISA that means a chip that provides it can never be competitive with ARM on power consumption.

We've already seen Intel and AMD narrow the gap considerably, in part by adopting designs pioneered by ARM manufacturers like hybrid big-little cores.

Another aspect that I think gets forgotton in the Steam Deck conversation is the fact that AMD graphics performance is well ahead of Qualcomm, and that is extremely important for a gaming device. I'm willing to bet that the next Steam Deck goes with another custom AMD chip, but the generation after that is more of a question mark.

RISC-V is another wildcard that could end up threatening ARM's path to total dominance.
