I wonder if the the lack of support is really the biggest obstacle to adoption, or will the inevitable (threat of) lawsuits from ARM and Intel et al help slow the acceptance and use... Having said that. It might gain traction first for use in designs that don't have external facing customers. Custom ICs and the like that aren't sold to others or in the little corners of designs that are sold to others but where the RISC-V core isn't exposed. And perhaps the time for widespread use of FPGAs in computation has come. RISC-V could definitely get widespread adoption there. Although, the lawsuits might still follow them there if it was perceived as a big enough threat to licensing revenue. Anyway, definitely interesting times for hardware!
