Columbia University professor Stijn Van Nieuwerburgh stated that by 2032, the United States may need to invest approximately $3.5 trillion annually in AI services, equivalent to 8.8% of US GDP, to justify the current massive investments in data centers. The risk is that the expansion of computing power could lead to a significant decline in the price and profit margins of AI services, making it impossible for related revenue to support the current scale of investment. AI still has the potential to bring significant productivity gains, but the economic benefits may not necessarily translate into returns for investors.
