Considering modern processors spend 4-5 years in development before public release, someone would have to be building the game changing RISC-V CPU right now.
Maybe he meant that development on RISC-V CPUs would start in earnest in the next 5-10 years?

Tenstorrent is working on Ascalon. Wei-han Lien (lead architect of M1 at Apple) is the lead architect. Ascalon is a RISC-V microarchitecture expected to be released in 2024, with similar performance to projected AMD Zen5 (also 2024), but lower power consumption. Ventana Veyron is due late 2023. A very high performance server chip AIUI implementing RVA22+V. Rivos has been working on something RISC-V, with a very strong team, for several years now. SiFive's next iteration of high performance CPUs is expected to be strong. Alibaba group has something in the works, too. And this is all just the tip of the iceberg. There's way more known projects ongoing, and even more that we do not know of.
- WatchDog 3y agoThe reason that processors take so long to develop, might have something to do with the complexity of the ISA, most of CPU development effort is spent on verification, if you have a simpler ISA, I would imagine that it makes verification easier.
