From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Indeed. If you did performance per watt, it would show even better.
The critical thing I saw here is that a RISC-V board is now outperforming a Pi 4. The price / performance just has to improve a bit more and RISC-V will be a viable alternative in the SBC market. I see it moving to laptops and tablets pretty quickly after that.
Totally independently, there are people trying to make RISC-V work for servers. As ARM has not really succeeded there, RISC-V may even beat them to it.
The place that I expect ARM to continue to dominate for quite some time is Phones. And x64 is not going anywhere for desktop and probably gaming for quite some time.
Performance / watt matters though and, as RISC-V improves, the long term picture for ARM especially gets pretty cloudy.
