Good morning. “Even the CEO’s job can be replaced by AI.”That was the WhatsApp message DBS Group’s board sent Tan Su Shan on the day they named her chief executive of Southeast Asia’s largest and most profitable bank. Tan shared the moment with me last week at Fortune’s Brainstorm AI Singapore conference — and her reaction landed like a challenge to the rest of the audience: “If the CEO can be replaced, so can everything else.”That mix of excitement and existential threat ran through two days of debate among more than 70 leaders from nearly 20 countries. Singapore’s digital minister Josephine Teo outlined her country’s AI strategy of carving a middle path between the U.S. and China, explaining how the city‑state of 6 million is shaping policy between Big Data superpowers. On another panel, executives from three of Asia’s most sophisticated data center operators debated Malaysia’s data center boom and the region’s prospects for satisfying the demand for energy. U.S. policy analysts also dissected the U.S.–China AI rivalry and Trump’s new AI action plan at the gathering. And digital artist Refik Anadol stunned the room with AI‑generated works that seemed equal parts data and dream.Other panels tackled hard questions: Is AI wiping out entry‑level jobs? Can it adapt to local languages and cultures? Will it narrow global inequality — or widen it? Leaders from Google, Microsoft, OpenAI, Walmart, Accenture, Rakuten, Indeed, and others weighed in, often bluntly.I left Singapore astonished by AI’s speed of change — and sobered by how much depends on leadership choices. Tan’s own advice to DBS employees, and perhaps to every executive navigating the shift, came down to four R’s: reinvent, stay relevant, be resilient, and act responsibly.Contact CEO Daily via Diane Brady at diane.brady@fortune.comThis story was originally featured on Fortune.com
