RISC-V is inevitable. ARM would do well to start building IP on the architecture before they're left in the dust by SiFive and friends.
Like, right now the best RISC-V cores are already faster than the A72 core on the Pi 4. A few years before and these same companies were only competing for the microcontroller market.
The Raspberry Pico M0 is almost as power efficient as the ARM Blackpill M4, some other RISC-V processors fall behind in that department but it's almost always a trade-off with speed. I must say the ARM's system on a chip walled garden philosophy is met with a lot of apprehension from me, especially in past examples like Mac products and Smart TVs where users sometimes resorted to building custom chip mounts and testing random inputs just to be able to eventually change firmware. Can't say I'm a fan of the company or happy about this development.
