Useful, sometimes impressive, but fundamentally passive. You asked, it answered. That model is getting replaced. Not gradually — the shift happening in 2025–26 is more structural than that. The Copilot model had a ceiling Copilots were built around a simple loop: human prompts, AI responds, human decides what to do next. The human was always the connective tissue between each step. Which worked fine for drafting emails or explaining code. But it doesn't scale to anything complex. If you want AI to help you ship a feature — not just write a function, but plan the work, write the code, test it, catch edge cases, and flag what it couldn't handle — the prompt-response loop breaks down immediately. You'd spend more time babysitting the model than doing the work yourself. Agentic systems are an attempt to fix that. Instead
