Ray Kurzweil: Singularity, Superintelligence, and Immortality | Lex Fridman Podcast #321

Kurzweil opens with the prediction that defines him: computers pass the Turing test by 2029, the singularity arrives in 2045. He recounts making the 2029 call in The Age of Spiritual Machines in 1999 — when Stanford convened an international conference of AI experts to assess it, and the average poll answer was a hundred years. From there the conversation ranges over brain-computer interfaces, nanotechnology, mind uploading and digital afterlife, the simulation hypothesis, and mortality — the full Kurzweil worldview, delivered as the large-model era began catching up with his timeline.
