For more than half a century, researchers have looked for ways to move past silicon by building electronics from molecules. The idea sounded simple and beautiful, but real devices turned out to be messy. Inside a working component, molecules do not act like neat, isolated pieces from a textbook. Instead, they form crowded, interactive networks where electrons move, ions shift position, interfaces change over time, and even tiny differences in structure can trigger strongly nonlinear behavior. The potential was exciting, but reliably predicting and controlling what a mo
