>Why not ARM then? Putting aside other advantages (open ISA, free license, ecosystem, no vendor lock-in), there are technical reasons. RISC-V is simpler. This matters a lot when you already have the complexity of radiation tolerance to put up with. Simplicity also lends itself to high assurance, through verification and formal proofs. In practice, we see how SiFive and Andes offerings beat ARM's own in performance and power efficiency, with a major area advantage (sometimes less than half!).
