Quote of the day by Carl Sagan: 'We've arranged a civilization in which most crucial elements profoundly depend on...' - thought-provoking quote by astronomer and host of Cosmos: A Personal Voyage explains why society depends so much on science and technology for growth and advancement

Quote of the day by Carl Sagan: Whether ordering groceries with a smartphone, consulting a doctor through a video call, or using GPS to navigate unfamiliar roads, most people interact with science and technology countless times each day. These innovations have transformed the way the world works, making communication faster, healthcare more advanced, and information more accessible than ever before. Yet the convenience of modern life often means people rarely stop to consider just how deeply civilization depends on scientific knowledge and technological systems.

Quote of the day today: Carl Sagan's warning about society's dependence on science and technology

Today's quote by Carl Sagan is, "We've arranged a civilization in which most crucial elements profoundly depend on science and technology," as per BrainyQuote.

Carl Sagan's quote reflects today's technology-driven world

Although the quote was made years before today's AI revolution and widespread internet connectivity, its message feels remarkably current. Modern society depends on science and technology for healthcare, transportation, communication, banking, education, food production, and emergency services.


Many of the systems people rely on every day operate quietly in the background. Satellite networks enable GPS navigation, cloud computing powers businesses, and scientific research continues to drive breakthroughs in medicine and renewable energy. Sagan recognized that civilization had become increasingly dependent on technologies that many people use but few fully understand.

Why scientific literacy matters more than ever

Sagan was a lifelong advocate for science education and critical thinking. His quote serves as a reminder that understanding science is no longer just an academic pursuit, it is an essential life skill.

As artificial intelligence, cybersecurity, biotechnology, and digital platforms become more influential, informed citizens are better equipped to evaluate information, make sound decisions, and distinguish facts from misinformation. Scientific literacy also encourages curiosity, problem-solving, and responsible innovation.

The responsibilities that come with technological progress

While technology has improved quality of life in countless ways, it has also introduced new challenges. Cyberattacks, misinformation, data privacy concerns, and dependence on digital infrastructure demonstrate that technological progress requires careful management.

Sagan believed that society should embrace scientific advancement while remaining aware of its responsibilities. Innovation can solve many global problems, but it also demands ethical decision-making, public understanding, and continued investment in education.
