While the sentiment is a bit harsh, the performance gap noted is real. RISC-V has a ways to go to catch up to ARM64 and then finally AMD64 but if the Apple M1 taught us anything, it's possible.

RISC-V shouldn't try to catch 40 years of spiral-development, but rather focus on something people can gather momentum around.

amd64 wasn't a great design, but provided a painless migration path for x86 developers to 64bit. Even Intel adopted this competitors architecture.

I like the company making a multi-core pseudo GPU card around RISC-V + DSP cores, but again copying NVIDIA bodged on mailbox style hardware is a mistake. It is like the world standardized around square-wheels as a latency joke or something... lol

Making low-volume bespoke silicon is a fools errand, and competing with a half-baked product for an established market is a failed company sooner or later.

I think people are confusing what I see with what I would like to see. An open ISA would be great, but at this point I can't even convince myself I'd buy a spool of such chips. =3
