To be fair, this is machine code, so it's what, 4-10 bytes for an instruction and two or three of these per line of high level code? So it's probably comparable to a few thousand "pages" of C code.

But it's still pretty amazing.

I think it more like 2-4 bytes per instruction[1]. Information density of machine code can be surprisingly high.

Of course, density can also be abysmal with current toolchains and practices.

Thank you for contextualizing this I was really trying to think about fitting an operating system into 12 pages...
