1. Large-scale models represent high-dimensional thinking, but to express and write them down, dimensionality reduction, or collapse and projection, is necessary. 2. In the AI era, aesthetics are even more important because aesthetics are high-dimensional and difficult to replace. 3. The concept of "I" is inherently the universe, self-sufficient, and inherently high-dimensional. However, once one cares about external evaluations, once one clings to the flashes of inspiration in one's mind (attachment), it collapses into a lower dimension. Why is Nvidia so expensive? It's a machine that accumulates and transforms the low-dimensional world into a high-dimensional one.
