Incoming links: RISC-V
This ISA basically completely dominated the smartphone market of the 2010s and beyond, but it started appearing in other areas as the end of Moore's law made it more economical logical for large companies to start developing their own semiconductor, e.g. Google custom silicon, Amazon custom silicon.
It is exciting to see ARM entering the server, desktop and supercomputer market circa 2020, beyond its dominant mobile position and roots.
Ciro Santilli likes to see the underdogs rise, and bite off dominant ones.
The excitement also applies to RISC-V possibly over ARM mobile market one day conversely however.
Basically, as long as were a huge company seeking to develop a CPU and able to control your own ecosystem independently of Windows' desktop domination (held by the need for backward compatibility with a billion end user programs), ARM would be a possibility on your mind.
- in 2020, the Fugaku supercomputer, which uses an ARM-based Fujitsu designed chip, because the number 1 fastest supercomputer in TOP500: www.top500.org/lists/top500/2021/11/It was later beaten by another x86 supercomputer www.top500.org/lists/top500/2022/06/, but the message was clearly heard.

They apparently even produced a real working small RISC-V chip with the flow, not bad.
The leading no-royalties options as of 2020.
China has been a major RISC-V potential user in the late 2010s, since the country is trying to increase its semiconductor industry independence, especially given economic sanctions imposed by the USA.
E.g. a result of this, the RISC-V Foundation moved its legal headquarters to Switzerland in 2019 to try and overcome some of the sanctions.
Leading RISC-V consultants as of 2020, they are basically trying to become the Red Hat of the semiconductor industry.
