History is much easier than prediction.

I'm with Jim Keller when he says that in time the fastest CPUs will be RISC-V ones.

I mean, Apple is different from pretty much every other manufacturer here. They collborated in the design of aarch64, and a rumored to own a lot of the base IP themselves which they've cross licensed with ARM. It's very close to AMD:Intel::Apple:ARM when it comes to aarch64. That heavily changes the licensing costs. My point isn't that RISC-V is markedly better, but instead that it's equivalent from a perf achievable from in the same nexus of PPA and NRE effort. So there's no reason for Apple to take the pain of a leap with no real gain, but NRE losses.

I would expect to see RISC-V Android phones (probably initially out of China, despite ARM China) within the next few years. They've been busy bees since RVA23 was ratified with a bunch of Chinese companies making changes to optimize AOSP for RVA23. I've also heard on the grapevine that NT already has a RISC-V port internally, but take that with whatever grain of salt you feel like. But Microsoft has already been contributing to the RISC-V specs (they contributed to Ztso for instance).
