That assumes that RISC-V is a competitive advantage over ARM and x86. While I have no particular grounds for pessimism about RISC-V, it seems a bit premature to assume that it's better in practice than those others.
Lots of companies are throwing their hat in trying to design a riscv core.
You can do a riscv startup, its much harder to do an arm startup and near impossible to do an x86 one
Introducing a new instruction set is an enormous undertaking, taking multi-decades typically. If anything, the adoption of RISC-V and its momentum is astonishingly fast.
