>>This is, essentially, a mega-gaffe by the semiconductor industry.
This is a bit rich I feel.
It has taken the world a *decade* to find this on what are the two most popular architectures (x86, ARM) which are open on the details of the involved HW (out of necessity for SW use).
The number of technical people and engineers who have seen this is not insignificant over that decade.
Yet it has taken so long to identify it.
Hindsight might be 20/20, but to call this an obvious gaffe is contrary to a decade of evidence.
