Sure. But you don't write a system only in assembly. The point, now buried in this silly thread, was alexchamberlain's nit that it wasn't "literally" true that all systems are built on top of C kernels (whether it be an OS kernel, firmware, whatever).
You can call me what you like and if you'd said "everything" instead of "literally everything", I would have let it slide. You were being quite misleading.
Given that you haven't provided a single counterexample, I can't see how I'm being misleading. All modern systems are built on C. All of them.
And for the record, I didn't call you anything. A "nit" is a pedantic correction, c.f "nitpicking". I could have said "quibble" too. It's a reference to your words, not you.
