The Financial Post reports in its Friday edition that the rapid emergence of artificial intelligence presents "the greatest investment opportunity and threat of our lifetimes," Brookfield chief executive officer Bruce Flatt warned investors Thursday, noting that as much as $5-trillion to $10-trillion are riding on the push to build out capacity quickly. The Post's Barbara Shecter quotes Mr. Flatt saying in a letter to shareholders: "What is clear is that we are in the midst of a transformation of how we live and do business. What is never clear is exactly how and when this will affect people and businesses." The global investment giant and its majority-owned Brookfield Asset Management are betting big on AI infrastructure, from data centres in England to U.S. semiconductor manufacturing. Mr. Flatt said the speed and scale at which AI is moving makes it more difficult than in past technological transformations to figure out who will make money, how they will make it and whether we are building too fast. "It is the sheer scale and speed at which this is happening that creates the challenge and opportunity," he said, adding that capital will be the ultimate decider in this story, and those who have it will win.
