Mary Daly, President of the Federal Reserve Bank of San Francisco, recently stated that the potential artificial intelligence (AI) bubble in the stock market may not threaten overall financial stability. Daly emphasized: "We should be wary of the idea that all bubbles are financial bubbles, and there is currently little evidence to suggest that the AI bubble belongs to this category." She pointed out that from a research and economic perspective, investments in the field of AI are more like a "beneficial bubble" - even if investors do not receive all the returns expected by early enthusiasts, they can still leave behind productive results rather than nothing. Specifically, Daly gave three reasons: first, the AI capital expenditure boom is driven by financially sound large companies, not a wave of high-risk startups, which does not pose a threat to financial stability; second, even if investors' enthusiasm is too high, it can still help the development of this transformative technology, similar to how the internet bubble burst but left behind internet technology; third, AI, like the iPhone, has transformative power, unleashing unknown opportunities and increasing overall economic productivity.
