> Note that neither are these micro-ops RISC (they are long, complex and specific to the chip, actually much closer to EPIC), nor was this micro-ops approach new.

I was mostly thinking about them as simpler - which is not the same as simple - but mostly in the larger context of it not being a religion where chip designers pick a side and never budge, when in reality everyone finds ways to use good ideas that make sense for their designs.

Chip designers design chips (I suspect you meant to emphasize microarchitectures), whereas ISA designers design ISAs.

An ISA designer's concern is to design a good ISA[0]. A good ISA will be chosen and loved by microarchitecture designers. This enthusiasm might then come off as religion-like.
