Rubin served as Treasury Secretary in the Clinton administration from 1995 to 1999, a period marked by rapid internet development. He also served as co-chairman of Goldman Sachs.
Rubin is particularly concerned about the "circular risk" within the AI ecosystem: "Some AI giants have made massive procurement commitments, and many suppliers have borrowed money based on these commitments. What happens if these companies fail to fulfill their commitments, or if the borrowing firms run into trouble? This is what we call circular risk."
He believes that if one party fails to meet its commitments, it could lead to a "blow-up," triggering chain defaults, and the risk of such impact cannot be ignored.

However, another guest at the same event, Michael Novogratz, founder of Galaxy Digital, believes AI is currently in "the biggest bubble of our lifetime," and the speculative frenzy will continue to heat up, making it still worthwhile for investors to participate.
He thinks that judging by price-to-earnings ratios, AI-related stocks are still cheap. "If you're not investing in AI, you might as well go home and stick your head in a bucket of ice water." (rc)
