This episode is a perfect allegory of what we are living through. Anthropic had to replace git for its monorepo www.anthropic.com/engineering/... . The reason: 2,500 merges a day in May, more than 30,000 in Sept.

Git was designed for humans who work offline.Their “devs” are now agents, connected all the time. Git’s superpowers became its kryptonite. The outcome of the redesign: checkouts 100x faster (a few seconds instead of several minutes).

We can keep plugging AI into tools built for humans, and be surprised when we hit the wall. Or reinvent everything for the agentic era, keeping humans where they are irreplaceable: understanding the business, deciding what to build, and framing what “done” means. That last part is pure engineering.
