> The x86 may live for a good while, but within a couple years there will be far more "computers" running ARM processors than x86.
x86 isn't Intel's highest volume ISA by a couple of orders of magnitude - 8051 is.
I suspect that x86 is behind several other microcontrollers.
I expect the CPU architecture landscape to change most radically as the lines become indistinguishably blurry between telephones, computers and entertainment consoles.
