In November of 2022, a webpage was posted online with a simple text box. It was an AI chatbot called ChatGPT, and was unlike any app people had used before. It was more human than a customer service agent, more convenient than a Google search. Behind the scenes, battles for control and prestige between the world's two leading AI firms, OpenAI and DeepMind, who now steers Google's AI efforts, has remained elusive - until now. In Supremacy, Olson, tech writer at Bloomberg, tells the astonishing story of the battle between these two AI firms, their struggles to use their tech for good, and the hazardous direction they could go as they serve two tech monopolies whose power is unprecedented in history. The story focuses on the continuing rivalry of two key CEOs at the center of it all, who cultivated a religion around their mission to build god-like super intelligent machines: Sam Altman, CEO of OpenAI, and Demis Hassabis, the CEO of DeepMind. Supremacy sharply alerts readers to the real threat of artificial intelligence that its top creators are ignoring: the profit-driven spread of flawed and biased technology into industries, education, media and more. With exclusive access to a network of high-ranking sources, Parmy Olson uses her 13 years of experience covering technology to bring to light the exploitation of the greatest invention in human history, and how it will impact us all.
