I was expecting this to go into the direction of "China has inserted itself as a state level actor into the development of RISC-V, don't use it". That would've been ridiculous as the US has been meddling with chips for a long time and we still use their stuff. Having chip designs or instruction set architecture out in the open would give me much more confidence in a chip that anything AMD, ARM, Nvidia, qualcomm or whatever out there release.

Of course open ISA doesn't mean the resulting chip will be open, but it's a step in the right direction.

Indeed. We should also develop ways to detect sabotage in the design and manufacturing stages so a user can verify their chip doesn't have a backdoor
