We live in a world in which we can talk about "strategic corporals," who have to be cognizant of the fact that decisions they make can have long-term strategic consequences.

On the other hand, we also live in a world in which the impact of individual actions can seem vanishingly small: reducing my carbon footprint might have no visible impact on anyone by myself.

The connections between action, strategy, and feedback are being rewired, and no one yet has a good way to describe how that new wiring works.
