Coding agents have genuinely changed how I work, and I don't think that is a controversial thing to say any more.

Claude Code, Codex, Cursor, Gemini CLI, Qwen, opencode - most people I know are using two or three of them, not one, and using them on different things at the same time.

That is a real change in throughput. It is also where a new problem shows up, and it is not the one people talk about.
