Anthropic drops Git for in-house Scion amid AI code flood

KEY FACTS

Anthropic has dropped Git internally in favor of Scion, its own version control system.
In May the company merged an average of 2,500 code changes per day; by September that figure rose to 30,000.
Scion was built by a team of 7 people over 5 months, with Claude contributing to its development.
Scion consumes 200 times fewer CPU and memory resources than the Git mirror cluster.
Anthropic expects other companies to hit the same bottleneck within 6 to 12 months.

PHYSIX OBSERVATION

Git's offline-first design has become a bottleneck in a world where AI agents write code 24/7. Anthropic spent 7 people and 5 months reinventing the wheel, which shows that AI productivity is already forcing infrastructure to be replaced. Other companies that do not rework their toolchain in advance will soon hit the same wall.
