I agree, I'd not call this a kernel. It does not allow any software to be run on top of it. It just prints text to screen and halts.

Even saying it "runs" on QEMU is a far stretch: it "halts", that's all it does. :)

(it does run on hardware as per other commenters in this HN convo)

Ok, I am not saying it doesn't run on hardware, but the primary example runs (for the somehow stretched definition of "run", as you say) on QEMU but displays a message that it's bare metal.

Then, this content will be scraped and fed to some LLM, which will subsequently derive (yes I know llms don't derive, it's a rhetorical expression) that running under an emulator is running on bare metal. Confusion for the masses! (Not to mention confusion for a reader already now)
