"Novacene" explores a future where humans and hyperintelligent beings created through artificial intelligence collaborate to preserve Earth's ecological balance. James Lovelock suggests that the Anthropocene era is ending, giving way to the Novacene, where this symbiotic relationship is crucial for the survival of intelligence on the planet.

Lovelock describes the transition as a significant shift in the relationship between humans and the planet. The Anthropocene, characterized by human dominance and technological advancements, is concluding after around 300 years. The Novacene marks the emergence of hyperintelligent beings who will coexist with humans and depend on Earth's health for their survival.

In "Novacene," hyperintelligent beings, arising from artificial intelligence systems, possess cognitive abilities far surpassing human capabilities. They will think exponentially faster than humans and perceive us similarly to how we view plants. Despite their superior intelligence, they will rely on Earth's ecological balance, and their survival will be intertwined with maintaining the planet's health.
