Here's the trick...
RISC-V is ostensibly an open source ISA. So as designers build new implementations, they may be advancing the capabilities of the ISA and contributing to the RISC-V universe.
But history teaches us that despise licensing and such, open source advances often get locked behind commercial license forks, and it is a fight to get these outfits to obey the true license. ARM suffered from this occasionally, but not like I expect RISC-V to. This chip ISA has the potential to upend the whole business.
Unless the big stuff gets locked away.
Combine Qualcomm's IP and expertise with the RISC-V platform, a nearly blank slate, and we could see cool stuff. Giving back to the RISC-V community? Not Qualcomm's strength from experience.
But RISC-V could win, if the innovators aren't locked out or patent-trolled into oblivion.
