Stephen Hawking addressing Royal Society

The video explores the possibility of intelligent life in the universe, highlighting recent experiments that suggest life may be common due to the abundance of organic molecules. However, the evolution of technological intelligence is rare and fragile, as evidenced by Earth's history. It took 500 million years for life to evolve and 2.5 billion years for multi-celled organisms to develop, with technological intelligence appearing only once. This rarity suggests that while life might be common, intelligent life is not.
