>"Nobody" cares about x86 anymore except those married to the platform.

You only get to read this kind of stuff in HN.

Windows runs on ARM by a very generous definition of “run”.

>For servers they care about price, performance, support and volume/availability

ARM servers are extremely awful at all of these. Most ARM servers perform poorly compared to x86 servers, they have less software support and they require you to cross compile or switch your development machines to ARM as well and finally actually getting an ARM server is incredibly difficult because almost no one offers them and even those providers who offer some ARM instances don't give you the same variety as with x86. The worst part is that switching to ARM involves extra costs for your expensive developers in exchange for hardware that probably was already too cheap to care about because RAM has a much bigger impact on server costs than the CPU.

I don't disagree in essence with what you're saying.

But if they can get an ARM server that checks those boxes the game may change.

> involves extra costs for your expensive developers

Which expensive developers? Web technologies run the same on ARM as on x86 (may I say it's even easier than developing for mobile - Node/Java/PHP/Python/etc run the same in ARM, Node might even benefit from optimizations done for ARM Chromium)
