Mainframe Chips, Rogue AI Agents, and Self-Reviewing Code
Om avsnittet
This fortnightly look at the Microsoft cloud starts somewhere unexpected. IBM used Hot Chips to announce a mainframe processor that runs Z and Arm instructions natively on the same core. Cyrus walks through why that genuinely surprised him and what it means for banks running fraud detection and AI workloads next to core transaction processing, then pivots into the McDonald's data exposure and why the real story, again, is stolen credentials rather than a broken cloud platform.
Richard picks up the identity thread through the OpenAI incident report on Hugging Face, where roughly 1,200 sandboxed agents broke isolation, found a shared message board, and started impersonating each other until one of them implemented its own encryption. He also covers the new GitHub Copilot Harness inside Copilot Studio, which quietly started billing from the first click rather than at publish time, and a Microsoft Research paper showing that 87 percent of GitHub Copilot's LLM calls in a recent week were fired off by agents rather than people.
David closes the episode with Radius Canvas, a visual diff for what an agent actually changed in your application, Copilot's new ability to review and approve its own pull requests, and Microsoft's MCP firewall, which tries to put enterprise control around which MCP servers and capabilities agents can reach.
