Sir Arthur Charles Clarke (December 16, 1917 – March 19, 2008) was a British science fiction writer, scientist, and futurist. Along with Isaac Asimov and Robert A. Heinlein, he is regarded as one of the 'Big Three' of science fiction. His notable works include 2001: A Space Odyssey, Rendezvous with Rama, and Childhood's End.
Clarke was not only an outstanding novelist but also a remarkably prescient technology forecaster. In 1945, he published a paper in Wireless World magazine proposing the use of geostationary orbit satellites for global communications — a vision that became reality 20 years later. The geostationary orbit is now known as the 'Clarke Orbit' in his honor.
Clarke's predictions were grounded in scientific literacy, spanning communications, the internet, artificial intelligence, and space exploration. Many of his ideas have been vindicated by subsequent technological developments. This site archives 17 of his most influential technology predictions and evaluates those whose deadlines have passed.

Clarke Predictions All Prophecies 17 Q&A entries in total
Geostationary Communication Satellites
Arthur C. Clarke: Three satellites placed in orbit approximately 35,786 km above the equator could provide global communications coverage. These satellites would orbit in sync with Earth's rotation, remaining stationary relative to the ground, serving as relay stations for radio signals.
Personal Communication Devices with Global Positioning
Arthur C. Clarke: In the future, everyone will have a pocket communicator that allows instant contact with anyone anywhere on Earth. This device will also let you know your exact position on the planet at any time.
Global Electronic Library (The Internet)
Arthur C. Clarke: There will be a vast electronic library where anyone at home can access all recorded human knowledge — books, magazines, newspapers, maps — through a console. You will simply press buttons to retrieve any information.
Video Calling
Arthur C. Clarke: In the future, people will be able to talk face-to-face through screens, seeing each other's expressions and movements as if they were in the same room.
Tablet Computer (Newspad)
Arthur C. Clarke: A flat, portable electronic screen used for reading newspapers, books, and documents. Users select and browse content by touching buttons on the screen.
Artificial Intelligence
Arthur C. Clarke: Highly intelligent computers will emerge that can understand human language, reason and judge, and may even develop self-awareness. The intelligence of such machines could ultimately surpass that of humans.
Telecommuting
Arthur C. Clarke: In the future, people will not need to go to the office every day. Through advanced communication technology, you can do all your work from home — meetings, documents, collaboration. The concept of cities will change as a result.
3D Printing and Replicators
Arthur C. Clarke: Future machines will be able to replicate any object. You simply provide a design blueprint, and the machine builds the physical object layer by layer from raw materials. This will revolutionize manufacturing.
Online Shopping and E-Commerce
Arthur C. Clarke: In the future, shopping will not require leaving home. You can browse product catalogs on screen, place orders, and goods will be delivered to your doorstep.
Space Stations
Arthur C. Clarke: Humans will build large permanent space stations in Earth orbit as outposts for scientific research and space exploration. Astronauts will live and work there for extended periods.
Space Tourism
Arthur C. Clarke: Ordinary citizens will eventually have the opportunity to travel to space. Space travel will no longer be exclusive to government astronauts, but become an expensive yet purchasable experience.
Bioengineering and Genetic Modification
Arthur C. Clarke: Future scientists will be able to modify the genes of organisms, create new life forms, and even improve human genes to eliminate diseases.
Space Elevator
Arthur C. Clarke: A cable extending from the equator to geostationary orbit, with electrically powered elevators running up and down to transport people and cargo, dramatically reducing the cost of reaching space.
Lunar Base
Arthur C. Clarke: Humans will establish a permanent base on the lunar surface for scientific research and resource development. The Moon will serve as a stepping stone for humanity's expansion into space.
Asteroid Mining
Arthur C. Clarke: Humans will mine mineral resources from asteroids. Asteroids floating in space contain vast quantities of rare metals and minerals, far exceeding the value of any terrestrial mine.
Human Mars Landing
Arthur C. Clarke: Human astronauts will set foot on the surface of Mars, the greatest space exploration achievement since the Moon landing.
Robot Servants
Arthur C. Clarke: Intelligent robots will serve as household assistants, capable of performing chores, caring for the elderly and children, and engaging in natural conversation with humans.

Geostationary Communication Satellites
Arthur C. Clarke: Three satellites placed in orbit approximately 35,786 km above the equator could provide global communications coverage. These satellites would orbit in sync with Earth's rotation, remaining stationary relative to the ground, serving as relay stations for radio signals.
On April 6, 1965, the world's first commercial geostationary communication satellite 'Early Bird' (Intelsat I) was successfully launched, precisely validating Clarke's 1945 concept. Today hundreds of geostationary satellites orbit Earth, and the ITU has named this orbit the 'Clarke Orbit'.
Personal Communication Devices with Global Positioning
Arthur C. Clarke: In the future, everyone will have a pocket communicator that allows instant contact with anyone anywhere on Earth. This device will also let you know your exact position on the planet at any time.
The proliferation of smartphones perfectly validated this prediction. Mobile phones were widespread by 2000, and GPS became a standard phone feature in the 2000s. The device Clarke described in Profiles of the Future (1962) closely matches the modern smartphone.
Global Electronic Library (The Internet)
Arthur C. Clarke: There will be a vast electronic library where anyone at home can access all recorded human knowledge — books, magazines, newspapers, maps — through a console. You will simply press buttons to retrieve any information.
The World Wide Web launched in 1991, and by 2000 the internet had become a global information infrastructure. Platforms like Google and Wikipedia realized Clarke's vision of 'pressing buttons to access all knowledge.' In a 1999 AT&T interview, Clarke reaffirmed this prediction was coming true.
Online Shopping and E-Commerce
Arthur C. Clarke: In the future, shopping will not require leaving home. You can browse product catalogs on screen, place orders, and goods will be delivered to your doorstep.
Amazon launched in 1995, and by 2000 e-commerce had become a mainstream business model. Today the global e-commerce market exceeds $5 trillion, and Clarke's 1962 description of 'browsing on screen, ordering for delivery' is routine for billions.
Space Stations
Arthur C. Clarke: Humans will build large permanent space stations in Earth orbit as outposts for scientific research and space exploration. Astronauts will live and work there for extended periods.
2001: A Space Odyssey depicted a massive rotating space station. In reality, the International Space Station (ISS) began assembly in 1998 and has been continuously inhabited since 2000. China's Tiangong station was completed in 2022. While current stations are smaller than depicted in the film, 'permanent orbital habitation' has been achieved.
Video Calling
Arthur C. Clarke: In the future, people will be able to talk face-to-face through screens, seeing each other's expressions and movements as if they were in the same room.
2001: A Space Odyssey depicted videophone technology. Skype launched video calling in 2003, and video calls became widespread after 2005. Today FaceTime, Zoom, and WeChat Video are everyday communication tools.
Tablet Computer (Newspad)
Arthur C. Clarke: A flat, portable electronic screen used for reading newspapers, books, and documents. Users select and browse content by touching buttons on the screen.
The 'Newspad' described in 2001: A Space Odyssey closely resembles the iPad released by Apple in 2010. Samsung even cited Clarke's novel and film as 'prior art' evidence in its patent dispute with Apple.
Artificial Intelligence
Arthur C. Clarke: Highly intelligent computers will emerge that can understand human language, reason and judge, and may even develop self-awareness. The intelligence of such machines could ultimately surpass that of humans.
HAL 9000 from 2001: A Space Odyssey is one of the most iconic AI characters in sci-fi history. GPT-3 launched in 2020, demonstrating AI's ability to understand and generate human language. ChatGPT sparked the AI revolution in 2022. Clarke's prediction of 'intelligent computers that understand human language' has been largely realized, though self-awareness remains unconfirmed.
Telecommuting
Arthur C. Clarke: In the future, people will not need to go to the office every day. Through advanced communication technology, you can do all your work from home — meetings, documents, collaboration. The concept of cities will change as a result.
In a 1999 AT&T interview, Clarke explicitly predicted telecommuting would become the norm. The 2020 COVID-19 pandemic accelerated this shift, with billions working from home worldwide. The explosive growth of collaboration tools like Zoom and Teams confirmed Clarke's prediction.
3D Printing and Replicators
Arthur C. Clarke: Future machines will be able to replicate any object. You simply provide a design blueprint, and the machine builds the physical object layer by layer from raw materials. This will revolutionize manufacturing.
3D printing technology developed rapidly from the 2010s, and by 2020 was widely applied in manufacturing, medicine (prosthetics and organ scaffolds), and construction (3D-printed houses). While not yet at the level of 'replicating any object' as Clarke described, the core concept has been realized.
Bioengineering and Genetic Modification
Arthur C. Clarke: Future scientists will be able to modify the genes of organisms, create new life forms, and even improve human genes to eliminate diseases.
CRISPR gene editing was discovered in 2012 and by 2020 was widely used in biomedical research. The 2018 He Jiankui incident (gene-edited babies) sparked global controversy. CRISPR inventors won the 2020 Nobel Prize in Chemistry. Gene therapy is now used to treat genetic diseases like sickle cell anemia.
Space Tourism
Arthur C. Clarke: Ordinary citizens will eventually have the opportunity to travel to space. Space travel will no longer be exclusive to government astronauts, but become an expensive yet purchasable experience.
Dennis Tito became the first space tourist in 2001. In 2021, Virgin Galactic and Blue Origin began suborbital tourism, and SpaceX's Inspiration4 achieved all-civilian orbital flight. By 2025, space tourism has become a growing commercial sector.
Robot Servants
Arthur C. Clarke: Intelligent robots will serve as household assistants, capable of performing chores, caring for the elderly and children, and engaging in natural conversation with humans.
The home robotics market has developed significantly by 2025: robotic vacuums and smart speakers (Alexa, Siri) are in millions of homes, humanoid robots (Tesla Optimus) are in development, and AI conversational ability (ChatGPT) enables natural language interaction. However, an all-purpose robot butler has not yet become reality.
Space Elevator
Arthur C. Clarke: A cable extending from the equator to geostationary orbit, with electrically powered elevators running up and down to transport people and cargo, dramatically reducing the cost of reaching space.
Lunar Base
Arthur C. Clarke: Humans will establish a permanent base on the lunar surface for scientific research and resource development. The Moon will serve as a stepping stone for humanity's expansion into space.
