Mike Hostetler, creator of Jido and ReqLLM, is back for round three. Jido 2.0 hit the top of Hacker News and took his docs server down with it, and Jido v3 betas are already on Hex. We get into agentic back pressure, why models write better declarative Elixir, why most actors don't need an LLM at all, durable workflows with Jido Flow, and the multiplayer harness he's building on OTP.

Plus Grok Bots and personal agents, reverse engineering bad IoT apps, and live questions from chat.
