When you consider a swarm one bee at a time this way, it starts to look like a heap of chaos. Each insect wanders around, using its tiny brain to perceive nothing more than its immediate surroundings. Yet, somehow, thousands of honeybees can pool their knowledge and make a collective decision about where they will make a new home, even if that home may be miles away.

Somehow we have evolved a way to switch between handling the here and now and contemplating long-term objectives. It may be no coincidence that most of the thoughts that people have during mind wandering have to do with the future.
