How Rodney Brooks might approach Neuroscience

Neuroscience. It’s the brain, right? The ultimate control system. And we, as engineers and scientists, spend an awful lot of time trying to reverse-engineer it. The big mistake, I think, is looking at the brain as some abstract computing machine, a silicon chip with meatware. That’s not how nature built it. Nature didn’t build it for elegance of computation; it built it for survival, for interaction with a messy, unpredictable world.

Look at a simple creature, like a fly. It’s got a minuscule brain, but it can dodge a swatter with uncanny speed. How? It’s not running complex algorithms. It’s a collection of simple, reactive systems, all firing in concert. Obstacle avoidance, predator detection, escape reflexes – they’re all wired in, honed by millions of years of evolution. It's all about the interaction. The fly’s body, its wings, its eyes, its nervous system – they’re all one integrated unit, sensing and acting simultaneously.

We need to build it to understand it. Trying to understand intelligence by just staring at brain scans, or writing endless lines of code that mimic some perceived "thought process," is like trying to understand flight by just looking at a diagram of an airplane wing. You need to build the wing, feel the air, see how it lifts. We need to build embodied agents, put them in the real world, and see how they learn, how they adapt, how intelligence emerges from the ground up. The brain isn’t just a disembodied processor. It’s a biological engine, intrinsically linked to a body, acting and sensing in the chaotic, glorious real world. Nature got it right. We just need to start building more of what nature built.
