In the embedded arena, Arm (the instruction set) would appear to be pretty replaceable. Arm and MIPS competed for the same business, Arm and RISC-V can do the same. There is nothing magical about any of them.

Arm (the corporation) can make some money for themselves by coming up with increasingly cool Arm cores to sell (a mission Nvidia could have aided immediately and with high impact, but... nevermind) but the instruction set itself is not especially important anymore. There's a lot less path-dependency for companies in the embedded arena than there is among, for example, desktop computer companies.
