Harness Engineering Is Cybernetics

Reading OpenAI's , I kept having a feeling I couldn't place. Then it clicked: I'd seen this pattern before. Not once — three times.

阅读 OpenAI 的，我一直有种说不出的感觉。然后突然明白了：我以前见过这种模式。不止一次——三次。

The first was

第一个是

James Watt's centrifugal governor

in the 1780s. Before it, a worker stood next to the steam engine adjusting the valve by hand. After it, a weighted flyball mechanism sensed rotational speed and adjusted the valve automatically. The worker didn't disappear. The job changed: from turning the valve to designing the governor.

在 1780 年代。在此之前，工人站在蒸汽机旁手动调节阀门。在此之后，加重飞球机构感知旋转速度并自动调节阀门。工人并没有消失。工作改变了：从转动阀门到设计 governor。

The second was . You declare desired state — three replicas, this image, these resource limits. A controller continuously observes actual state. When they diverge, the controller reconciles: restarts crashed pods, scales replicas, rolls back bad deployments. The engineer's job shifted from restarting services to writing the spec the system reconciles against.

第二个是。你声明期望状态—三个 replicas、这个 image、这些 resource limits。控制器持续观察实际状态。当它们分歧时，控制器进行协调：重启崩溃的 pods、扩展 replicas、回滚坏的 deployments。工程师的工作从重启服务转变为编写系统协调的 spec。

The third is now. OpenAI describes engineers who no longer write code. Instead they design environments, build feedback loops, and codify architectural constraints — then agents write the code.

第三次是现在。OpenAI 描述了不再写代码的工程师。他们设计环境、构建反馈循环、codify architectural constraints——然后智能体写代码。
