Web Summit's final day: Huang's exit, AI bubble, and US debt fears take center stage

Jensen Huang's resignation as Nvidia CEO, AI bubble risks, and US debt concerns dominated the final day of the Web Summit in Lisbon, with a panel warning that public debt markets could trigger the next financial crisis. Huang stepped down after revelations of extramarital affairs, with US intelligence suspecting one woman of spying for China, claims Beijing rejects. CFO Colette Kress is interim CEO, and Nvidia stock fell over 30% from its October peak. Panelist Adam Kobeissi called the exit a "net negative for investors." Economist James Galbraith suggested Chinese technology could undercut Nvidia, tentatively betting on China to win the AI race. Kobeissi warned US interest payments consume 19% of revenue, citing a "100% chance of bankruptcy" on current paths, though he avoided predicting an imminent 2008-style crisis.
