Could be. Then again, today's main architectures are all decades old; they get
refined but not redone.
Emulation of new architectures on old ones goes back quite a long time. I've seen a
document from 1964, describing the emulation of the Electrologica X8 (which came out
around 1964) on its predecessor the X1 (which dates back to 1958).
