Nope, engineers are a couple levels DOWN from the designers.
Typically CPU designers have little idea how the latest gate-technology works. They know it exists, understands it's benefits and weaknesses and based on a philosophy, they make CHOICES.
Those designers could not possibly have foreseen triads or VLIW or Vector Registers but they ensured that their basic design was flexible enough for implementations of all kinds to be build, used, discarded yet at the heart of the design nothing had to change. code written in 1983 works fine even on the very latest CPUs. Lots of x86 design ideas have come and gone but it doesn't matter because all of them were still 100% backwardly compatible.
Backward compatibility only works because someone thought about it AT THE START.
It took longer, cost more, made design more difficult and forced trade-offs. BECAUSE the core philosophy was BACKWARD COMPATIBILITY! EVERY descision made had to first ask 'will this be backwardly compatible'. THAT is a design philosophy in action.
That is why someone using a computer to deride philosophy is an oxymoron.
