Good thinking there, but it's from 1985, no more vintage than ARM
(also 1985) and a whole lot newer than x86 (1978).
IMO, thinking of architectures as vintage is probably fallacy.
Implementations, sure, but architectures? Lots of processors we'd never
consider "vintage" today (ARM is a good example) are implementations of
architectures that are decades old. This is sorta necessary, as it
takes time, lots of time (as you know) for software to catch up. Only
in the past 5-6 years or so have the GCC back-ends started generating
really good code for ARM, for example.
