Huang Renxun said that OpenAI's 100 billion investment "may be the last time". It sounds like a signal that the AI craze has come to an end - but for the old leeks, just listen to this "big shot warning" because every time the giants shout empty, they are fighting for their own shipment time. From hardcore data, $100 billion may sound like a lot - but for AI infrastructure, it's just a ticket. Training a GPT-5 level model requires tens of thousands of H100 graphics cards, with each card costing over $30000. This does not include data center, energy consumption, and talent costs. AI is not a game that ordinary people can afford to play. Every time a giant in history shouted empty, the result was similar. In 2000, Bill Gates said that the Internet was a foam. As a result, Microsoft rose for another 20 years. In 2022, Musk said AI was dangerous, but Tesla is all in AI. The 'warning' of giants is often to buy time for their own layout - when they say 'maybe the last time', they are often preparing themselves. It is counter intuitive that this "AI foam theory" is the biggest risk for retail investors. When everyone believes that AI will collapse, it is precisely when institutions are quietly increasing their positions. The valuation of AI is indeed high, but it cannot withstand the fact that it can really make money. Poor cognition determines poor wealth - it's not that AI is incapable, it's that you don't understand how AI can make money. From a macro perspective, AI, like the Internet, is a new generation of infrastructure. The Internet was also called a foam when it was born, and later changed all industries. AI is the same - now is just the beginning, far from the end. The real question is: do you choose to embrace change or do you choose to be eliminated by change? So the ultimate question is: Do you believe in the "warning" of giants, or do you believe in your own judgment?
