Dwarkesh Patel interviews Richard Sutton, reinforcement learning pioneer, Turing Award winner and author of The Bitter Lesson. Sutton argues LLMs are a dead end because they cannot learn on the job, and that continual learning from experience will require a new architecture.

CNN report on bodycam footage of former Mesa police officer Philip Brailsford shooting unarmed Daniel Shaver in an Arizona hotel. Brailsford was later acquitted of murder charges.

Additional camera angles of the 1988 Sandia National Laboratories rocket-sled test in which an F-4 Phantom was crashed at about 500 mph into a block of reinforced concrete. The footage shows the aircraft disintegrating against the wall.
