If you haven't yet, read Matt Shumer's viral post Something Big Is Happening. In it he describes how knowledge work can now mostly be done by AI with less and less human intervention. That pace of change is faster and more significant than ever. A year ago, a task that took a human ten minutes could be completed by AI without human help. 🤯 As of November 2025 based on Claude Opus 4.5; five hours. Five hours of human expert level work completed by AI without human help.
Most if not all of OpenAI's GPT-Codex-5.3 was written by itself.
Read that again; OpenAI's system improved itself the way a human dev team would.
And it did it without human help until it was satisfied based on its own standards. Self-administered, recursive improvements. This is "big" as Matt states. No hyperbole.
What does this mean for all knowledge work, not just product management?
To me it means start documenting every aspect of your work flows, build an AI agentic system that can perform your tasks for you, and conduct and orchestrate like Leopold Stokowski.
