In the latest development from Silicon Valley, the startup Harmonic, led by co-founders Tudor Achim and Vlad Tenev, is pioneering the creation of artificial intelligence (AI) systems that don’t rely on guesswork. These advanced AIs, exemplified by a bot called Aristotle, are designed to verify their own mathematical calculations, setting a new standard for reliability in automated responses. In a demonstration, Achim presented Aristotle with a complex problem involving a grid of numbers, which the bot not only solved correctly but also confirmed with a self-generated verification program. This self-verification ability contrasts sharply with typical AI behaviors, where bots like…

As Jim Covello, head of equity research at Goldman Sachs, drove down Highway 101 this month, billboards screaming about artificial intelligence only reinforced his suspicions. From “Writer Enterprise AI” to “Speech AI,” these signs looked eerily similar to the pre-crisis cryptocurrency craze. Covello has become a leading voice of caution on Wall Street about AI. His research paper, which questions the return on investment for the projected $1 trillion in AI spending, has sent shockwaves through the market. He argues that current generative AI, which can summarize text and write code, is prone to errors, raising questions about its ability…
