Why we're in an AI bubble and what comes next: Ray Dalio, who predicted the 2008 crisis, explains the 80-year economic cycle driving wealth gaps, geopolitical conflict, and potential collapse. He identifies five forces reshaping economies and reveals which assets protect your wealth when systems fail. Bubbles burst when investors with borrowed money must suddenly sell assets to pay debts, causing cascading price collapses and widespread unemployment that harms real people through job losses and reduced spending. Cash is the worst long-term investment because inflation erodes purchasing power faster than interest rates compensate, making diversified portfolios (stocks, gold, bonds, real estate) essential for wealth protection. AI will eliminate jobs faster than new ones emerge because unlike tractors that freed labor for different work, machine intelligence replaces cognitive abilities—the last advantage humans had over technology. The next world order will likely have two regional superpowers (US and China) rather than one dominant power, with conflicts resolved through economic pressure and technology control rather than military warfare.
