I'd like science to have made enormous progress in the future. I think it could enable agriculture to develop while consuming a tiny amount of water, which would help a lot of developing countries. Science could also, thanks to human genetic manipulation, ensure that from the moment a baby is born, it receives a vaccine that would give it lifelong immunity against all known diseases. We could also do away with fossil fuels for our vehicles, and replace them with a new, non-polluting form of energy, which would not damage the planet in its manufacture and would be of minimal cost to the user. And, finally, let's dream a little: understanding between peoples.
