risc-v is much more reasonable for countries like china.What I want to emphasize is this: Instead of paying license fees for outdated x86 architectures, it would be much more beneficial to allocate those resources to universities. If you're paying for a license but can't generate a return on that investment quickly, then something is wrong.
You are completely misunderstanding China's goal. They want the expertise, being self-sufficient, while taking what they can so they don't start from 0.
Risc-V is arguably risky, so they have their hands on everything at the same time so they're sure they have a winner.
Markets don't matter. They want to develop the technology and have the talent to achieve it, fast.
For x86, supporting multiple companies would be more difficult, as they would need a license for the ISA (which Zhaoxin inherits from Via).
