I shrunk down into an M5 chip

Marques Brownlee walks viewers through a bold thought experiment: shrinking himself to the scale of a modern microchip to visualize just how small transistors have become. He starts by recalling how every generation of Apple chips, from M1 to M5, is associated with ever higher transistor counts, and uses a Blender-powered world to physically scale down his own size by 100x. The early segments place him at human scale, then at the size of a keyboard key, illustrating how the MacBook Pro deck becomes a city block in miniature and how eight terabytes of RAM and storage could fit into that tiny world. As the scale tightens, he moves into the micrometer range, then down to nanometer territory, comparing transistor sizes from 1948 up to a hypothetical 2026 M5 chip. He ties the visual journey to Moore's Law, explaining how the transistor count doubles roughly every two years and how this relentless miniaturization enabled laptops, Wi-Fi, and internet-era computing to shrink from rooms to pockets. The video culminates in an atom-by-atom vista, where 3nm and even 2nm transistors sit at the edge of perceptibility, and the process of photolithography is briefly explained as a light-based etching method that makes billions of transistors possible inside a device you can hold. Throughout, Marques credits the human ingenuity behind the scale shifts and highlights Epic Spaceman’s collaboration as an inspiration, while inviting viewers to ponder the future trajectory of semiconductor technology and the limits of Moore’s Law.
