Every now and then a new technology comes along that changes everything – electricity, computers, potentially AI. In mid-19th-century America, that technology was the steam locomotive. It knitted the US economy together, driving the nation’s industrialisation during the Gilded Age. But along the way, it also caused one of the biggest financial crises in American history. FT Alphaville editor Robin Wigglesworth tells his co-host, FT columnist Gillian Tett, the story of the great railway bubble that ended in the Panic of 1873. It’s also the story of the spectacular rise and fall of Jay Cooke, the greatest banker of his day, who lost a fortune betting on a railroad that would eventually span the North American continent – just not in time to repay its debts. Robin and Gillian discuss what lessons the financier’s fate holds for the investors gambling on today’s AI boom.
