A core abstraction in early Unix systems was the principle that 'everything is a file', enabling heterogeneous devices and kernel resources to be manipulated via uniform read/write interfaces. This paper explores how an analogous unification is emerging in contemporary agentic AI. We trace the evolution from Unix to DevOps, Infrastructure-as-Code, and finally autonomous software agents, highlighting how file-like abstractions and code-based specifications collapse diverse resources into consistent, composable interfaces. The resulting perspective suggests that adopting file- and code-centric interaction models may enable agentic systems that are more maintainable, auditable, and operationally robust.

翻译：早期Unix系统的核心抽象原则是“万物皆文件”，使得异构设备和内核资源能够通过统一的读写接口进行操作。本文探讨了类似的统一化趋势如何在当代自主AI中逐渐显现。我们追溯了从Unix到DevOps、基础设施即代码，最终到自主软件代理的演进历程，重点阐释了类文件抽象与基于代码的规约如何将多样化的资源收敛为一致且可组合的接口。由此形成的视角表明，采用以文件和代码为中心的交互模型，有望构建出更具可维护性、可审计性及运行鲁棒性的自主系统。
