big "Look what they need to mimic a fraction of our power" energy. the original DOOM impl is ~40k lines of C and a bit of assembly and is also a full software renderer. My Codex /goal that has been running for like 40 hours that is now 100K+ lines of code now is a pure Swift Doom source port. It'll be the first, source accurate, software renderer for Doom that is fully in Swift. No OpenGL, Metal, SceneKit, no nothing. Just Swift.
