Having a "majority" isn't really different from what we have now, and it includes the downside of a more robust monoculture.

And to be clear here, I'm not anti RISC-V. I am very highly skeptical, given how frequently we see things like code size critics responded to with 'but it will be faster', which isn't really an answer,

The same thing happened here. Hand wavy "the market" and "orthogonal way" doesn't communicate anything meaningful, and or worth some clear downsides at present.

Finally, "the goal" is really "a goal or vision" as expressed by proponents. It's not really one in the objective sense.
