Joe Rogan Experience #2155 - Brian Redban

Joe Rogan welcomes longtime friend and Kill Tony producer Brian Redban for a loose, wide-ranging conversation. They spend much of the episode on artificial intelligence, repeatedly querying ChatGPT-4o live about whether AI should govern the country and debating open-source vs corporate-controlled AI. The talk veers into plastics and microplastics found in every human testicle, the decline of testosterone and fertility, and theories about technology feminizing humanity. Other tangents include the explosive success of Kill Tony selling out arenas, kangaroo fights, a deep rabbit hole on fertility doctors who used their own sperm and attempts to hybridize humans and chimpanzees, lab-grown meat bans, and a long enthusiastic stretch on electric cars including the Porsche Taycan.
