Quick review of Long Bets
"Long Bets is a nonprofit foundation that calls itself an “arena for competitive, accountable predictions.” It lets anyone make a prediction and take wagers on it, with the proceeds going to a charity named by the winner. The bets made so far are from $200 to $10,000, on topics ranging from the driving habits of Americans in 2010 to whether the universe will stop expanding. Mitchell Kapor, the software guru, is betting that in 2029 no computer will have passed the Turing test (by conversing so much like a human that you couldn’t tell the difference). The physicist Freeman Dyson’s money is on the first extraterrestrial life’s being found somewhere other than a planet or its satellite."
Note : my prediction (257) is still open "Hydrocarbon fuels will be the "fuel of choice" for personal transportation for the next 50 years"
