In this episode, Lucas and Luna explore the tiny transistor that acts as the fundamental building block of every modern chip. They trace its evolution from a simple on/off switch to the nanoscale marvels inside today's processors, discussing how engineers have shrunk it from 10 micrometers to just 3 nanometers, and the challenges of leakage, heat, and quantum tunneling. Using Intel's 1971 4004 chip as a starting point, they show how transistor density reached over 50 billion on a single GPU by 2022. The conversation then dives into the latest research into gate-all-around (GAA) transistors and new materials like 2D molybdenum disulfide that could keep Moore's Law alive. Along the way, they discuss the economic implications—each new node costs billions to develop—and why transistor design remains the most important unsolved problem in hardware engineering.
