AI has evolved from a rubber duck and source of copied snippets into a useful coding assistant that can produce working code. Its value is not only in its answers: explaining a problem to it can clarify the problem for the developer, and quick guidance on routine tasks can break procrastination. But the benefit depends on experience. Developers still building fundamentals risk accepting code they cannot assess; working through problems before turning to AI helps them learn. Experienced developers are better positioned to recognize when generated code is misguided and correct it. The author warns that companies may favor seniors because AI can already execute many tasks expected of junior programmers.
AI makes code easier to produce, but does not take responsibility for system design or maintenance. Given broad instructions or too little context, it makes assumptions, adds unnecessary abstractions, and tends to expand rather than simplify. Small, incremental requests, clear constraints, and a strong test safety net help keep its output manageable. Developers must still monitor coupling and cohesion, refactor, and understand the code they retain. Used carefully, AI can make iteration and testing faster; used carelessly, it accelerates complexity and decay. The central lesson is that speed alone is a poor measure of progress: good software requires deliberate design, active simplification, and time spent understanding what has been built.
