AI is a five-layer cake.

The following only records some opinions of others and some of my own thoughts. These thoughts will not be comprehensive, may even be naive, and certainly cannot provide direct guidance or advice for investment: Jensen Huang, in his blog post "AI is a 5-layered cake" and the Cosmos large model released at the beginning of the year during CES, directly points to one issue: namely, data elements will no longer be a key factor participating in the development of productivity. Of course, the realization of the word "will" here spans a very long period of time. The collection of data elements and the energy required for computing power will eventually reach a dynamic equilibrium within a certain timeframe. The predictability and creatability of data refer to learning physical laws through an understanding of the physical world. From a philosophical perspective, it is akin to a form of metaphysics.
