ARM is most dominant in the microcontroller space with the Cortex-M devices. Literally billions of them are made every year.

It's not about the number of ARM cores shipping today, but tomorrow. If RISC-V tools are about as good as ARM and the cores are cheaper it will become the preferred instruction set somewhere in the future.

Seems in this age of open source tools the instruction set is mostly commodity anyway.
