The speaker discusses the possible risks of high technology, such as nuclear war, ecological collapse, and unforeseen accidents, as well as the likelihood of a future dominated by inorganic lifeforms, whose behavior is determined by the laws of inorganic chemistry.
The three big global challenges today are nuclear war, climate change, and ecological collapse. Nuclear war is the most complex issue due to its disputed existence and its potential catastrophic consequences.
The prevalence and dominance of organic lifeforms on Earth may soon be shifting as AI technology advances, leading to the possibility of creating completely inorganic beings or part organic, part inorganic cyborgs.
Professor Yuval Harari predicts that Homo sapiens will not be around in 200-300 years, but suggests that accepting our own mortality can help us face the potential mortality of the entire species.
