AI That Acts: Devin Fusion, Persimmon, Programmable Worlds & Amodei’s Slowdown Call

Can AI-generated worlds remember what happened off-screen? How do dual-agent setups reduce costs? In this episode of Attention Span, we break down the biggest shifts in AI’s ability to understand, reason, and act in the physical and digital world. We dive into Alaya’s programmable world model, real-world vs. simulated robotics with Telexistence and Skild S1, Cognition’s Devin Fusion and SWE-2, and the heated frontier slowdown debate between Dario Amodei and David Sacks. Hosted by Ksenia Se (founder of Turing Post). Covering September 7–13, 2026. 👇 Which topic should we cover in a deep-dive episode? Let us know in the comments!
