>I'm sure we're all at the edge of our seats hoping to experience an efficiency revolution, and that this can be given to us with this one weird trick of changing ISAs... but it's not happening. At least not with ARM, or RISC-V or any other contemporary architecture that isn't x86.

You seem to miss that RISC-V being better is besides the point.

RISC-V's massive success was unavoidable, due to its open specification and free license.

The ISA did not need to even be good, just decent.
