I think the RISC-V Vector Extensions are very elegant. However, I'm more interested in what hard core practitioners think and the ones I follow are nonplussed.

I'm reminded of a compliment for Vishy Anand's middlegame technique. He plays very well with the knight pair.

Here’s the opinion of probably THE most important ARM engineer of the 1990s and 2000s, Dave Jaggar who developed the ARM7TDMI, Thumb, Thumb2.

Check at 51:30 where he says (bringing up the topic of RISC-V himself) “I would Google RISC-V and find out all about it. They’ve done a fine instruction set, a fine job […] it’s the state of the art now for 32-bit general purpose instruction sets. And it’s got the 16-bit compressed stuff. So, yeah, learning about that, you’re learning from the best.”

RISC-V really shines when the op-compression extension and macro-op fusion are taken into account.

Many of the early critiques of RISC-V have not considered that. And many points become entirely moot in light of these techniques.
