What are peoples visions of the future? In the 1930's people thought there would be flying cars etc? Does anyone actually think this is possible within the next 100 years? Security would be a massive concern if people could just fly anywhere and everywhere!
Will global cooling begin over the next 20-30 and hurt our food supplies?
Do you think humans will make it to Mars by 2050 and how long do you think it will take to colonise the whole solar system?
Will the population of earth hit 20 billion by 2100?
What expectations do you have and what would you most like to have invented?
