Geoffrey Miller is an evolutionary psychologist at the University of New Mexico, bestselling author, and one of the world's leading experts on signaling theory and human sexual selection. His book "Mate" was hugely influential for me personally during my dating years, so I was thrilled to finally get him on the show.

In this episode, Geoffrey drops a bombshell 50% P(Doom) assessment, coming from someone who wrote foundational papers on neural networks and genetic algorithms back in the '90s before pivoting to study human mating behavior for 30 years.

What makes Geoffrey's doom perspective unique is that he thinks both inner and outer alignment might be unsolvable in principle, ever. He's also surprisingly bearish on AI's current value, arguing it hasn't been net positive for society yet despite the $14 billion in OpenAI revenue.

We cover his fascinating intellectual journey from early AI researcher to pickup artist advisor to AI doomer, why Asperger's people make better psychology researchers, the polyamory scene in rationalist circles, and his surprisingly optimistic take on cooperating with China. Geoffrey brings a deeply humanist perspective. He genuinely loves human civilization as it is and sees no reason to rush toward our potential replacement.
