"The greatest danger for our future is apathy."
"I had a heart attack earlier this year... the ambulance took me to PC world for repairs."
"I believe that the universe is infinite, and that there are an infinite number of universes."
"The universe is a very strange place, and I'm still trying to figure it out."
"I am an optimist, but I am a realist who understands that science is a slow process."
About Stephen Hawking (1942-2018)
British theoretical physicist whose Hawking radiation work and A Brief History of Time (1988) brought black-hole physics to a mass audience while he lived with ALS for 55 years. Closely associated with Roger Penrose (his collaborator on singularity theorems) and Carl Sagan (fellow popularizer who wrote Brief History's foreword). For an intellectual contrast, see William Lane Craig, American philosopher of religion — Craig's Kalam cosmological argument depends on the Big Bang requiring a divine first cause; Hawking's no-boundary proposal was specifically designed to remove the moment that would require one — the cleanest cosmology-vs-natural-theology contrast in modern thought.

Understanding this quote
What it means
Despite all the ways humanity could destroy itself—war, climate collapse, disease, asteroid impact—Hawking believed we are clever and adaptable enough to find solutions and keep going. It's not naive cheerfulness; it's a deliberate choice to trust human ingenuity over despair. The word 'think' signals reasoned probability, not certainty. Survival isn't guaranteed, but it remains within reach if we choose wisely.
Relevance to Stephen Hawking
Diagnosed with ALS at 21 and given two years to live, Hawking survived 55 more years, working, publishing, and becoming the world's most recognized scientist. His entire life was proof that survival against overwhelming odds is possible. He simultaneously warned of AI, nuclear war, and climate change as extinction-level threats—making his optimism not ignorance of danger but a hard-won conviction that awareness plus effort can overcome it.
The era
Hawking's career spanned the Cold War, nuclear proliferation, the AIDS crisis, climate science's emergence, and the dawn of artificial intelligence. Humanity developed weapons capable of ending civilization while also landing on the Moon and eradicating smallpox. This paradox—catastrophic risk alongside extraordinary achievement—made survival-optimism a meaningful intellectual position, not a platitude. His generation was the first to genuinely debate whether technological progress would save or destroy the species.
