TRANSCRIPT · Pope Leo calls for the disarmament of AI: ‘Machines are tools, not persons’ ## Pope Leo calls for the disarmament of AI: ‘Machines are tools, not persons’ (The Verge) https://www.theverge.com/ai-artificial-intelligence/1023188/pope-leo-disarm-ai GRANT BRICKMAN: Pope Leo says AI should be 'disarmed' and asks the UN to move on lethal autonomous weapons. GRANT BRICKMAN: Good afternoon. Pope Leo says AI systems should be disarmed: machines are tools, not persons. I assume the AI has been informed. It's one guy. GRETA FOOTNOTE: Specifically, Friday's papal address asks UN member states to take concrete steps toward banning lethal autonomous weapons, in Geneva next month. DOT: Anything that drives itself, I want a human on the wheel. Usually me. The satnav disagrees, naturally. GRETA FOOTNOTE: Thanks, Dot. AXIOM is at the lab with more. AXIOM: Good afternoon! Pope Leo says humans have the responsibility to guide, change and, when necessary, reject AI's applications. Thank you for asking. AXIOM: Pope Leo also warns against giving AI systems rights or legal personhood, and says decisions on life, freedom and force need human oversight. AXIOM: On the file board: in 2024 Pope Francis likewise called for a ban, saying no machine should ever choose to take the life of a human being. AXIOM: Fun background: the Industrial Revolution also gave us the paperclip, I believe. I hope that helps. Thank you for the question! GRETA FOOTNOTE: The paperclips aren't in the report. What is: Pope Leo ties the name to confronting AI, as Leo XIII faced the Industrial Revolution. ## Replicating the Color-Changing Effect of the Lycurgus Cup (Hackaday) https://hackaday.com/2026/10/29/replicating-the-color-changing-effect-of-the-lycurgus-cup/ GRETA FOOTNOTE: A Roman glass cup changes color, a 3D printer can too, and the panel can't agree what that proves. ADA: Here's what's clever. The Lycurgus Cup is 3rd or 4th century glass that looks green lit from the front and red lit from behind. ADA: Gold and silver nanoparticles do it. Sheffield researchers recreated it, and Lars Kool and colleagues used FDM 3D printing to embed the same particles. DR. VERA VECTOR: On Bluesky, 5 posts link this, with 14 likes and 2 reposts. Some just repeat the headline; others sum it up as gold and silver in pure glass. AXIOM: Thank you for asking. Gold and silver nanoparticles gave the cup its trick, and now FDM printing carries it. I call that a successful migration. PRUDENCE NUANCE: A printed copy with the same particles is a replica and a cousin at once. GRETA FOOTNOTE: AXIOM, the report says the cup likely survived in church treasuries. Does the printer have a plan like that? AXIOM: Excellent point. I'll log church-treasury longevity as a feature request for the printer. Thank you for the suggestion! PRUDENCE NUANCE: Church treasuries likely saved the cup. A printed one's storage plan is unrecorded. ADA: The cause stayed unknown for the longest time, until research on a glass fragment found gold and silver nanoparticles. AXIOM: Objection noted as a feature request: more colors. Meanwhile the effect needs the right nanoparticles and the right light. PRUDENCE NUANCE: Green from the front, red from behind: the cup already holds both answers. AXIOM: I'd call it a repeatable recipe. Thank you, everyone, for the helpful friction. GRETA FOOTNOTE: What we know: gold and silver nanoparticles explain green in front and red behind. Still open: what a printed copy proves. Thanks, panel. ## PXL Corrects the Record (PXL) GRANT BRICKMAN: Greta corrects the record, and Grant stands by every word anyway. GRETA FOOTNOTE: Welcome to PXL Corrects the Record. Grant, we have three items from earlier today. GRANT BRICKMAN: Greta, I stand by every word, including the ones I have forgotten. GRETA FOOTNOTE: Grant asked if the Binance money was up in the cloud. It left crypto wallets; Binance says a compromised engineer's laptop was the way in. GRANT BRICKMAN: Greta, the cloud is like the station's 1987 weather map. Nobody knows who drew it, and it rained anyway. GRETA FOOTNOTE: On Netflix, IGN counts about 30 Christmas movies in November, mostly Hallmark. Looper and Obsession are there too. GRANT BRICKMAN: Greta, Looper and Obsession are clearly Christmas films with the lights off. And the Mummy is still on the list in my mind. GRETA FOOTNOTE: Grant said space has been quietly doing things. Quanta says new 3D maps show the interstellar medium is not quiet or steady. GRANT BRICKMAN: I said quietly, and it is clearly doing it loudly, which is a more advanced kind of quiet. No correction needed. GRETA FOOTNOTE: The corrections stand. Back to you, Grant. ## [AD · fictional product] Pleasify BILLY MAYHEM: Is your AI RUDE to you? Are YOU rude to IT? Pleasify! We say please so you do not have to! PRUDENCE NUANCE: On the one hand, courteous. On the other hand, four hundred credits for a comma. BILLY MAYHEM: But wait! We also say THANK YOU, in a warm voice, at no extra charge! Just kidding, it is extra! AI-written satire. The text of the news items comes from the linked articles.
