I think RISC-V isn't really targeting general-purpose machines. They are targeting special-purpose machines. Think Google TPU built from a RISC-V scalar unit + custom tensor unit. 64-bit flash controller without a multiplier or MMU, but with specialized instructions to accelerate error correction. Something to manage the DDR training at startup. Embedded security widgets. Things like that. This is a development machine announcement for the companies who are building such custom hardware.
