He is being replaced by current DeepMind CTO Vikkal Corre. But that was not even the most shocking departure. Jeff Dean, Google employee number 30, a level-11 engineer (a rank held by only two people in the company's history), left alongside fellow senior fellow Sanjay Ghemawat to co-found a new startup called Discovery Loop.

The hosts noted a nostalgic post about his slide deck design — those blue, tacky-looking slides that signaled something legendary was about to ship. Discovery Loop's mission is to automate scientific research using recursive learning loops. The idea: an AI system sends a prompt, iterates on it until it reaches a difficult answer, and then uses that loop to improve itself. The company plans to start with AI research itself — building models that can reevaluate and build better versions of themselves — and then move on to grand challenges like
