An interview with Google senior research economist Mihai Codreanu on the next bottleneck in AI for Science, based on the AI in Science: Early Insights study by Google, DeepMind, and MIT FutureTech.
- Corpus of 15M Gemini interactions, 2,690 specialized models, and a survey of 637 US/UK researchers
- Researchers save 7 hours/week with AI, but nearly half report a growing backlog of untested hypotheses
- Charts: over two years, 43.5% of scientists saw bottlenecks shift downstream (lab/writing) vs. only 13.8% upstream; 89.3% spend under 10% of saved time auditing
- Key takeaway: AI speeds up individual tasks, but turning predictions into validated discoveries remains constrained
