Coders End, from Typers to Thinkers (etsd.tech)

After a decade in development, the author argues 2025 marked a turning point: AI now handles most of the typing, so the human role has shifted from coding to architectural thinking. To illustrate this, they released MCP-Pointer, an open-source MCP server that lets developer tools point to browser DOM elements—MCP being an emerging community standard for AI-tool integration. The core claim: code itself is no longer “precious”; what matters is how systems are designed, named, assembled and specified. Concrete technical wins show the shift in practice. Building MCP-Pointer involved orchestrating multiple local MCP (STDIO) processes behind a single WebSocket server, which required a leader/follower election system; setting up multi-package tooling with packaging, signing and automation; and rewriting a Chrome extension’s element selector after refining abstractions (i.e., writing a better spec). These examples underline a broader implication for the AI/ML community: productivity gains come from delegating implementation to models while humans focus on interfaces, protocols, system design and tooling. The future of web development, the author contends, is architectural—demanding clearer abstractions, standards like MCP, and human-led design work that shapes how agentic coding tools are used.
