The bottleneck has moved.
Coding agents such as Claude Code, Codex, and Cursor now write most routine code well. Most teams already use them, but ad hoc: on laptops, unsupervised, with no consistent checks on what they produce.
Leading engineering organisations now run their agents inside structured software factories. Every task takes the same path from ticket to merged change, with the same checks every time.
Writing code is no longer the slow part. The system around the agents is. A small team with a good factory can out-ship a much larger team without one.
The agents are the workers. The factory is everything around them.
