If I was seeing RISC-V get widespread adoption in consumer-grade hardware, I'd be thinking about it (granted, having X86-64 and ARM on the market could make room for a third competitor compared to the 15-year x86 hegemony.) But I don't see a push for that, and there probably won't be unless RISC-V delivers better results than ARM. Keep in mind that you and I probably care more about CPU architecture than the average gamer.
