The software factory is already here.

Writing code by hand is becoming an elective activity. You can still love it, teach it, and get very good at it. But an organization that pays people to type every implementation themselves is choosing craft over economics.

An agent can produce a hundred plausible directions before your team finishes debating the first one. That does not make judgment obsolete. It makes selection the most expensive decision in the room.

A model that helps improve the next model sounds like a loop. It is not one. Until the work can propose a change, run an experiment, judge the evidence, and survive a bad result, you have a clever assistant waiting on a human research process.

Launching more coding agents is easy. Building a system that knows when they should not start, continue, or ship is the actual work.

Every check passed. The new behavior still escaped three of them. That is not a testing failure. It is an inventory failure hiding behind a green result.

A new model can beat yesterday's favorite before your procurement meeting ends. That is useful. It is also a terrible foundation for an operating plan.

An agent can write ugly code that is perfectly fit for a five-second tool call. The failure begins when that same code crosses into the product and nobody makes it earn the right to stay.

An agent can make every test pass and still leave the codebase worse than it found it. Correct behavior is the entry fee. The factory also has to control what each change does to the system behind that behavior.

Tell an agent to use fuzzing, property tests, or formal methods and it may use the tool perfectly while proving almost nothing. The label changed. The verification strategy did not.

Bad code does not eventually become too bad to continue. It keeps accepting one more shortcut, one more patch, and one more feature until the business discovers the limit for it.

The build-versus-buy debate asks for one answer and then tries to make that answer last forever. AI makes that mistake more expensive, not less.

When agents can change production all day, undo cannot remain the plan you invent after something breaks. Reversal has to be part of the factory that shipped the change.
