It&#39;s the Halloween episode, and Mark and David turn down the lights to swap stories. They cover Halloween traditions and the horror movies they love (and the horror movies that scarred them). Mark tells a few personal stories he still can&#39;t explain. David talks about seeing horror movies way too young and finding it difficult to suspend disbelief today.Mark and David veer into fun topics like:<ul><li>Spook vs Gory Halloween</li><li>Dia De Los Muertos</li><li>Mark&#39;s haunted childhood home</li><li>Positing a supernatural detector</li><li>The &#34;magic&#34; of Halloween</li><li>Horror movies and shows mentioned</li><li>The Exorcist</li><li>The Conjuring</li><li>Poltergeist</li><li>Jaws</li><li>Aliens</li><li>Ex Machina</li><li>Siren</li><li>The Ring</li><li>The Twilight Zone</li><li>Stranger Things</li><li>The Haunting of Hill House</li><li>Good Luck, Have Fun, Don&#39;t Die</li></ul>

Is Nolan’s Time Genius or Nonsense? Memento, Inception, Interstellar, and TenetMark and David discuss Christopher Nolan’s recurring use of time across films with guest Mark Wiberg, debating whether it’s brilliant or overly complicated. Wiberg ranks Interstellar highest for its time pressure on humanity, relativity set pieces like Miller’s planet, and the emotional video-message sequence, wchhile noting issues with early dialogue, character development, and the final reunion. They revisit Memento’s reverse structure, unreliable narrator, manipulation of Leonard’s memory, and the reveal that he chooses to continue the quest. Inception’s nested dream time is criticized for exposition and an ambiguous ending, though praised for ambition and effects. Tenet divides them: Davidt calls it a favorite for entropy reversal, determinism themes, and set pieces, while others find it cold or confusing. They end with broader thoughts on time stories, determinism vs free will, and recommendations. Check out Wiberg&#39;s DJ Butterz Youtubehttps://www.youtube.com/@DJButterz

This week Mark and David ostensibly talk about the book and movie versions of Solaris. Solaris is a story that asks some deep questions like:<ul><li>What are the limitations of Science?</li><li>How do you determine if an entity is conscious?</li><li>What are 50 ways to kill your re-animated loved one?</li></ul> However, Mark triggered David by asking about AI. This causes David to go on a long and tedious explanation of why LLMs are not conscious. Which is basically a recapitulation of:https://gracefulatheist.com/2026/06/07/humanism-and-ai/They discuss this aritcle in Verge: AI bots started a religion — humans immediately followedhttps://www.theverge.com/ai-artificial-intelligence/975017/ai-spiralism-chatbot-movementCounter points to my argumetns on LLMs:Are LLMs conscious?https://preposterousuniverse.com/podcast/2026/08/10/363-chandra-sripada-on-how-llms-and-humans-are-cognitive-cousins/Do LLMs plan?https://www.youtube.com/watch?v=locKEKxG3osOther topics Mark and David veer into:<ul><li>The Odyssey</li><li>Morality</li><li>Re-dos</li></ul>
