> They've already migrated MacOS to a RISC architecture, Have they? I certainly think you have a point about microcontrollers. I find it very doubtful RISC-v would supplant ARM on the high end anytime soon. The licensing fees are pretty peanuts compared to the cost of designing your own cores and even the big players have been struggling to come up with anything that could compete against ARMs designs (besides Apple of course). Also it’s not at all clearer what incentives would Apple have to switch to RISC-V? Sure they could do it.. what would they gain though?
