AI coding agents are changing the way software is built. But as AI becomes capable of writing, testing, and modifying code, one question becomes increasingly important: How much of software engineering should we actually delegate to AI? The evolution from traditional development to AI-assisted and agentic software engineering. For years, artificial intelligence helped developers write code faster through autocomplete, code generation, and chat-based programming assistants. But AI coding agents are different. Modern agents can increasingly take a development task, inspect a codebase, modify multiple files, run tests, investigate failures, and iterate toward a solution. That changes the conversation. The question is no longer: "Can AI write code?" It clearly can. The more interesting question is: "What becomes the most valuable skill for a software engineer when writing code is no longer the hardest part?" AI Coding Agents Are Becomi...
