Of course, as these many additional sets of instructions get fleshed
out, were the ISA to be implemented, such an ISA would lend new
meaning to the term "dark silicon", since, having so many instructions
available, they could hardly all be in common use.

Indeed, the situation could even be described with the catchy book
title...
