If this is Google's automatic-idiocy bot, DO NOT TRUST IT. Never ever
trust anything from an LLM bot.

I have seen posts about a highly experimental Raspberry Pi OS
experiment which ran NetBSD on one Arm core and RISC OS on another.

However the thing is that the RasPi is not an Arm computer. It is a
VideoCore running ThreadX with an Arm co-processor. So this technique
might not scale. Also, Risc OS is inherently single-core so that makes
life a tiny bit easier... two SMP OSes would be highly tricky.

On a related note, I do not like Youtube, but this talk is highly relevant.
