I don't think this is correct. 128-bit RISC-V has nothing to do with SIMD, at all. It was created to future-proof RISC-V wrt. exascale distributed computing, where even a full 64-bit address space might be insufficient.
Maybe. The point is that you can encode more per unit, so you can batch more things in one go. Is not exactly SIMD as is today, but is also the same idea.
