- Age of Ultron? Maybe. Anthropic’s latest data shows AI isn’t just assisting; it’s building its own successors. Claude-generated code now hits 80% of merges, accelerating dev cycles eightfold. We’re witnessing recursive self-improvement in real-time—models handling 12-hour coding tasks and near-perfect scientific replication. It’s not sci-fi; it’s the new factory floor. But as Jack Clark warns, the hardware of thought is outpacing our oversight tools. We need robust verification protocols before we let the robots run the assembly line unchecked. The rocket is fueled, but do we have the steering mechanism? Stay sharp, engineers.
