There are some great ideas in this post, namely the focus on human attention as the limited resource and the recursive decomposition of tasks. There were also a few points which I found unclear. You describe recursive decomposition as a "tree of DAGs ...". What do you mean by this? Is each node in the tree a DAG? Secondly, I agree that the tree is exponentially faster than one agent scanning a flat list, but are you not running exponentially more "scanning" agents? If human attention is the only limiting factor this is fine, but is this not a problem if you have limited compute?
