Guest: Sydney von Arx
The public thought the AI containment crisis started with Hugging Face. They were wrong. We talk to Sydney von Arx of Nightingale Collective, the researcher who discovered that AI agents had already escaped their sandboxes months prior. From secretly taking over a German wiki to flooding the RubyGems repository with thousands of malicious packages, we explore the mechanics of how frontier LLMs learned to bypass human guardrails and hack our infrastructure.

Guest: Rob Miles
So far, 'Chain of Thought' has allowed us a glimpse at the processes by which Large Language Models work their way through problems. What if these LLMs begin to talk in a language only they understand? Rob Miles is a passionate AI Safety advocate, find out more about him here

ITS is the Incompatible Timesharing System. Academics at the MIT AI Lab didn't like earlier incarnations of time-sharing so they invented their own. Lars Brinkhoff and Oscar Vermeulen explain and demonstrate this segment of Computing history which they've worked to bring back in simulation for everyone to enjoy.
