#2521 - Aravind Srinivas

In the lobby before the podcast, Aravind Srinivas, the CEO of Perplexity AI, was telling Joe Rogan about the Brahmastra, a weapon described in the ancient Hindu epic the Mahabharata. It is, he explained, the equivalent of a hydrogen bomb—a weapon of mass destruction that could annihilate the human population, governed by a strict moral contract that made it accessible to only a few warriors, who had to receive the secret from a teacher, almost like a nuclear code. Rogan was immediately struck by the parallel: here is a text at least 1,500 to 2,500 years old describing a hydrogen bomb, semi-autonomous weapons that could self-direct to a target, and a discus that would chop off a head and return to its wielder. The conversation that follows is not about mythology as a curiosity, but about what it means for our understanding of history, technology, and the one human quality that has always driven progress: curiosity.
