RISC-V is an open source ISA but there is not yet and open source RISC-V CPU. RISC-V is interesting and I believe that there is a market for it, although not very large since RISC-V is not innovative enough, is not a leap forward in anything and basically uses old technology with an "open source ISA" sauce on top of it. So yes, RISC-V will grow, but not no great heights. For spectacular new CPUs one needs new technologies which are being developed. Rex Computing is developing the NEO CPU which is try to get rid of the memory bandwidth bottleneck while going for a chip with 256 cores. Mill Computing is developing a very innovative CPU that has solutions for many small and large issues that slow down performance of CPUs of Intel, AMD, IBM, Oracle and HP, while also targeting to reduce the power needs by 10x. These CPUs will surprise the market.
