“At that point, I'm not running agents anymore. I've become the scheduler, deciding who does what. I'm the memory, holding what every one of them is doing, and I'm the reviewer, checking all of it. One human, three roles, six contexts. It does not scale.”

He responded by arranging the agents in a hierarchy where each sees only a scoped slice of context, so he reviews only what reaches the top. Quoted from YouTube’s auto-generated captions.
