The world’s most accomplished tech founders and business leaders are betting hundreds of billions on AI with extraordinary conviction. Meanwhile much of the investing world thinks they’re making a massive mistake. The irony is hard to ignore. An investment industry where very few have historically managed to beat a passive index is now questioning the judgment of the people building the technology and running the businesses that will put it to work. Maybe the investors are right. Maybe the builders are. But I can’t remember a time when the stakes were this high and the two sides saw the future so differently.
