Humankind is on the road to nowhere

Humankind evolved out of a hunter-gatherer past, using stone, fire and then metals to survive in a harsh yet sustainable environment. Although they had no concept of it, their existence was self-sustaining and energy-balanced. All physical effort was expended in catching food and basic survival, which left no energy surplus. Without energy surplus there could be no specialization, no society and no economy.
