The Globe and Mail reports in its Saturday edition that the Milken Institute's Global Conference in Beverly Hills was filled with confidence and energy over artificial intelligence. The Globe's James Bradshaw writes that this theme, however, made some of the world's top chief executive officers visibly uncomfortable. A few days at the Milken conference, referred to as "the zoo" by some senior executives, is a thrilling yet jarring blend of high-stakes global finance, bullish predictions and conspicuous glamour. One of the biggest draws was Nvidia CEO Jensen Huang. Several CEOs joined him in the camp of AI optimists. BlackRock CEO Larry Fink, however, said he thinks the supply of electricity and chips to fuel AI will be so constrained that it will soon be possible to trade futures contracts on compute power. He said: "I don't believe we're moving fast enough. There is not an AI bubble. There is the opposite. We have supply shortages." Other speakers acknowledged that there are risks to employment and cybersecurity, and the full impact is hard to predict, but said forging ahead is the only option. IBM's Gary Cohn said AI's importance to national security and military supremacy dwarfs near-term fears about disruption.
