Three key positions in the AI era

In an era where artificial intelligence has become a core variable in global competition, what truly deserves to be written about is not just the technological breakthroughs themselves, but the individuals who stand in different key positions and redefine boundaries. This series of articles selects Maiyue Cheng, Jensen Huang, and Sam Altman not because of their public profiles, but because they respectively represent three aspects: energy systems, computing power engines, and AI applications. Through these profiles, we attempt to answer a more fundamental question: as computing power expands rapidly, what real-world conditions are quietly constraining its limits? This is not only a technological issue, but also a financial issue concerning industry, institutions, and the future order.
