My point wasn't that it's impossible, but that it creates a massive layer of overhead. Previously the project "state" lived in the developer's head; now for the agent to be effective, you have to constantly offload that state into design docs and task files. The job shifts from "writing code" to "managing external memory" for the agent. Those who have mastered this (like you) are indeed flying, but those trying to just chat with the code without this discipline are hitting a wall
