All The Times Science Fiction Became Science Fact In One Chart

• You have an error with Waterbeds. The "Actual Discovery" is repeating the line above it about visual flight simulators.Not to mention the actual discovery of waterbeds was in 1832. I love Heinlein, but he erroneously gets credit for this one all the time.

• electric submarines were in use since at least the Holland in 1900; 

• the "discovery" of From the Earth to the Moon should be Apollo 8 in 1968, not Apollo 11 in 1969 (especially since Apollo 8 more closely matched the mission from Verne's book); 

• and Arthur C. Clarke invented communications satellites in a non-fiction proposal from 1945, not in 2001.

• Bionic limbs, predicted WAY earlier than 1972, I'd have to check source but you had them in the Cybermen from doctor who in 1965 and I'd wager a lot before that

• I remember an Ursula K. Le Guin short about clones ("Nine Lives") and I wonder who was the first to come up with that (I saw genetic manipulation on the chart, but it's not really the same).

• I'd add Wikipedia to Douglas Adams' 'predictions'. A massive electronic encyclopedia, accessible everywhere through small devices (phones/tablets/eBooks), updated wirelessly by a huge number of contributors and covering a vast range of topics. Also, a reputation as somewhat unreliable!

• Credit cards - There were similar systems before the year noted, but they were limited to credit with a particular merchant. The date given is for general-use cards good at a variety of participating merchants.

• Solar energy - I don't know if calculators were the first use of photovoltaic cells or not, maybe they were, but solar energy per se was in development long before the cited book was written, though I believe it was mainly for heating and such.

• Communications Satellite - The first dedicated to communications were the passive reflector Echo 1 launched in 1960, followed by the first active sat Courier 1B the same year. The first to actually relay communications was Project SCORE in 1958. Clarke proposed the idea in a non-fiction article published in 1945.
