Jeff Dean Left Google After 27 Years. Here’s Why. Jeff Dean spent nearly 27 years at Google helping build the infrastructure and AI research that shaped modern computing. Now he’s starting Discovery Loop with longtime collaborators to explore a bigger question: What happens when AI doesn’t just assist researchers, but helps drive scientific discovery itself? Run experiments. Learn from the results. Decide what to test next. Repeat — at a scale humans alone can’t match. And that’s why this story matters. AI isn’t saturated. We may still be in the very early innings. The biggest opportunity might not be another chatbot — but using AI to accelerate science, healthcare, finance, education, manufacturing and entire businesses. The people building at the frontier seem to think there’s still a lot left to build. #AI #ArtificialIntelligence #JeffDean #Google #DiscoveryLoop
