One technology breakthrough for ARM over x86(which has little room left for improvement at this point), could be a watershed moment for the chip manufacturers
This stuff doesn't exist because of a particular vendor or ISA; it's a mainstream feature for modern application platforms. Many ARM systems achieve similar ends through a kind of hypervisor / shadow OS that can't readily be disabled by the device owner [1].
Unfortunately, enabling this stuff seems to be the deal with the devil you have to do in order to become a mainstream platform. I highly doubt that ARM will supplant x86 without also offering something that is functionally equivalent to ME.
