I stumbled upon an AI pancake machine in a corner of the Haidian Library. This is an edge model based on a physics engine. It doesn't do Vibe Coding, but it has top-notch "batter fluid dynamics" computing power. It has no illusions, only the brutal aesthetics of classical control theory. This determinism fascinated me, so I decided to try the high-computing version with "double eggs." But as I glanced at the market software, I suddenly understood the meaning of "edge computing"; being on the brink of bankruptcy, I had to think twice about spending money, so I quietly opted for a single egg instead. When I got the pancake, I found the packaging said: "Made by robots, it may not have that human touch, but we are always learning." I instantly felt relieved; this wasn't just selling pancakes, it was clearly about reinforcement learning training. The machine is trying to align with human preferences for the complex notion of "human touch" by continuously making pancakes. And I am using my dwindling purchasing power to provide its model with the last bit of real Human Feedback.
