Philosophy majors who learned to code are having a field day with this one. The classic allegory of Plato's Cave gets a hardware makeover: Chrome (yes, the RAM-eating monster) sits chained in the cave, only perceiving the shadows of "Virtual Memory" and "Address Translation" cast by the MMU—basically the bouncer that translates your program's fantasy addresses into actual hardware locations. Meanwhile, outside in the "real world," we've got Physical Memory basking in sunlight with Firmware and CPU living their best lives.

The MMU (Memory Management Unit) is literally on fire here, which is accurate because it's working overtime to maintain this beautiful illusion. Most developers spend their entire careers in that cave, blissfully unaware that pointers don't actually point to physical addresses. And honestly? That's fine. The moment you leave the cave and start dealing with firmware and bare metal, you realize the shadows were actually pretty comfortable.
