Are there not similar techniques to search trees that are used here? Obviously you wouldn't enumerate all options but you'd think you could guess at some practical ones then guess options between the most promising. Either way, it just feels "imagination" is making it sound like an entirely new approach when heuristically pruned search trees could be described in the same way to me.
It also paves the way to algorithms which can solve problems by repurposing available actions for achieving unintended goals, and by creating new high-level actions from low-level ones.
