 "summary": "In this Diary of a CEO interview, 87-year-old investor Jeremy Grantham argues that AI has created the biggest investment bubble in history and warns that a major crash — potentially a 70% decline in the high-flying stocks — is imminent and could play out over the coming years. He advises selling US stocks and especially US tech, moving instead into non-US equities, bonds, cash and precious metals, and dismisses crypto as worthless. Grantham critiques SpaceX and Elon Musk as textbook market-peak euphoria, describes the Magnificent Seven as locked in a brutal winner-take-all AI war, and raises alarm about AI safety. He also links the market bubble to deeper crises: extreme wealth inequality, a dissolving US social contract, and a 'baby bust' in which toxic chemicals are driving a collapse in sperm counts and fertility. He closes by urging listeners to read the data, exit the most dangerous part of the market now, and brace for tougher times.",
