Stephen Hawking's warnings on existential threats to humanity

Physicist and cosmologist Stephen Hawking, known for his research on black holes and Hawking radiation, left several warnings regarding the future of human civilization. His primary concerns included nuclear war, genetically modified pathogens, climate change, and the uncontrolled development of artificial intelligence.

Hawking frequently emphasized the dangers of global warming, warning that uncontrolled climate change could reach critical tipping points that would be extremely difficult to reverse. Years after his passing, the world continues to face record temperatures and extreme weather events. His life was also marked by his battle with amyotrophic lateral sclerosis (ALS), a disease he lived with for decades despite initial medical predictions that he had only a few years to live.
