엘론 머스크, 양자 미세소관, 그리고 의식 있는 기계를 위한 경쟁

A recent Quanta Magazine piece by John Pavlus examines a burning question: how close are humanoid robots to becoming more sophisticated than humans? While neural networks on fast GPUs have turbocharged computer vision and reinforcement learning, allowing robots to perceive environments better, a massive gap remains between "moving" and "being." Engineers have moved beyond the "linear inverted pendulum" model, using deep reinforcement learning to act as whole-body controllers. As Pulkit Agarwal puts it: “To have robots which work like humans, I think we have to master physics.” This means moving beyond maps and truly understanding force and inertia. At Google DeepMind, Carolina Parada emphasizes VLA (Vision-Language-Action)—giving a robot one cohesive "brain" instead of three that don't get along. Meanwhile, Jonathan Hurst focuses on Quasi-Direct Drive (QDD) motors—robotic "muscles" that balance strength with sensitivity. Yet, Russ Tedrake argues the bodies are already good enough; the problem is the brain. He points to teleoperation: when a human wears a VR headset to "drive" a robot, it can fold laundry or pick up a grape perfectly. The hardware works; the autonomous software is the bottleneck. The "Secret Sauce" vs. The Fundamental Flaw While Tedrake proposes Large Behavior Models (LBMs)—applying the logic of ChatGPT to movement—others are skeptical. Frank Park believes our mathematical foundation for robot "brains" is fundamentally flawed. Gill Pratt even worries we are using AI to make robots run before we understand how walking actually works. The level of sophistication we are matching is the HUMAN BRAIN, which is "CONSCIOUS." Aaron Barbey (Notre Dame) notes that while neuroscience explains networks, it struggles to explain how a "coherent mind" emerges. The 11-Dimensional Sandcastle The Blue Brain Project (EPFL) found that neurons don’t connect in simple lines. Using algebraic topology, they discovered "cliques" forming geometric structures in up to 11 dimensions. They describe this as a multi-dimensional sandcastle: Stimulus: Learning a fact builds high-dimensional towers. Structure: It scales from 1D rods to 5D+ cubes. Disintegration: Once the information is "understood," the castle vanishes, leaving the neurons ready for the next task. The "Unknown" and the Simulation We are building things we don’t truly know how to operate, inspired by the "Unknown"—the human brain. Elon Musk’s vision is to leverage AI and robotics to eventually discover what lies outside this simulation. This connects to Sir Roger Penrose and Stuart Hameroff’s Orch-OR theory. They suggest microtubules inside neurons perform quantum computations. Penrose argues that consciousness isn't a biological accident, but a ripple in the very structure of spacetime. Cognitive scientist Donald Hoffman takes this further, suggesting space and time are just a "user interface." In his view, our bodies are just "icons," and the real "You" exists in a network of consciousness outside of perceived time. The Path Forward Can we build humanoids close to being human if we don't first study how a human brain develops—like in babies? Or must we deep-dive into philosophy to bridge the gap? If the brain is an 11-dimensional quantum processor, perhaps our current "brains" of silicon and code are merely scratching the surface of what it means to be "Better Than Us."
