What is your criteria to measure this by and over what time scale? In 5 years, I have doubts we will see even 5% penetration of riscv on platforms which end user software runs (outside of China). I wish I could be more optimistic, but after paying attention to the standards process due many years and seeing the landscape evolve, I've become pesemistic on the matter. Even after hardware is competitive, software support will continue to lag. This culminates in security, performance and power challenges that would regress user experience compared to arm and limit adoption by device makers.
