I stumbled upon an AI-powered pancake machine in a corner of the Haidian Library. It's an edge model based on a physics engine. It doesn't do Vibe coding, but it boasts top-tier computational capabilities for "batter fluid dynamics." It doesn't offer illusions, only the brute-force aesthetics of classical cybernetics. This certainty fascinated me, so I prepared to try the high-performance "double egg" version. But a glance at my stock market app made me suddenly understand the meaning of "edge computing." On the verge of bankruptcy, I needed to calculate my spending, so I silently switched to a single egg. Upon receiving the pancake, I noticed the packaging read: "Made by a robot, it might not have the same authentic feel, but we're constantly learning." I instantly understood. This wasn't just selling pancakes; it was clearly performing reinforcement learning training. The machine was trying to align with humanity's complex preferences for "authentic feel" by continuously making pancakes. And I was using my remaining purchasing power to provide its model with a final bit of genuine human feedback. It was learning to empathize, while I was learning to remain calm and composed.
