Could Silicon Valley Billionaires Cure Aging? With Aleks Krotoski

What it might mean – biologically, socially, and philosophically – if death becomes optional? Humanity has long dreamed about the idea of immortality. And in 2026, many believe that dream could soon become a reality. The world’s most powerful technologists and investors are pouring billions into engineering immortality itself. For these modern-day immortalists, aging is no longer an inevitability – it’s a technical glitch that can be hacked, reversed, or eradicated altogether. On today’s episode, award-winning broadcaster and academic Aleks Krotoski speaks to host Carl Miller about the moguls, effective altruists, geroscientists and entrepreneurs who are seeking to disrupt death. Drawing on Krotoski’s new book The Immortalists, they discuss encounters with radical life extensionists transfusing their teenage son’s blood, transhumanists who want to upload consciousness to the cloud, biohackers flogging AI-powered wellness apps and billionaire kingmakers building brand-new nations.
