Quoting James Shore
James Shore 强调，AI 编码代理必须降低代码维护成本，否则编码速度的提升反而会导致长期维护负担剧增。如果编码输出速率加倍，维护成本需减半；输出速率提升三倍，维护成本需降至三分之一。数学关系显示：输出加倍且维护成本加倍时，总维护成本将翻四倍；输出加倍但维护成本稳定时，总成本仍翻倍。这警示开发者，AI 工具应在提升效率的同时，以成反比的方式减少维护开销，避免用短期速度换取永久性债务。

Your AI coding agent, the one you use to write code, needs to reduce your maintenance costs. Not by a little bit, either. You write code twice as quick now? Better hope you’ve halved your maintenance costs. Three times as productive? One third the maintenance costs. Otherwise, you’re screwed. You’re trading a temporary speed boost for permanent indenture. [...]
The math only works if the LLM decreases your maintenance costs, and by exactly the inverse of the rate it adds code. If you double your output and your cost of maintaining that output, two times two means you’ve quadrupled your maintenance costs. If you double your output and hold your maintenance costs steady, two times one means you’ve still doubled your maintenance costs.
