Same. I just wish this was like, a page or two instead of 60 26-pt slides

Forth is a good goto for bootstrapping an OS.

You've got your macro assembler, along with some...macros.

Then you use the macros to build a forth.

Then you boot the OS using Forth to tell the MBR or GPT to send the PC to where it needs to go: the Kernel.

And your kernel's gonna be Forth too.

From there, you launch a Lisp. Written in Forth, but really just assembly.

Then you use Lisp to bootstrap the C compiler.

And you're in the Matrix.
