I would like the world to stay the same like current times but with slight differences like removing any nuclear weaponry and wars are non existent, and, world hunger would no longer exist. We would have some great innovations like a food duplicator but to duplicate your food you will need to pay so that the person that grew the food would get money. It would also be illegal to chop down trees and each month you must plant one meaning that forests will continue to exist. If an illegal act is done the court will decide the defendants fate if the defendant is guilty the police will put a collar on the criminal and due to innovated tech the collar can scan the criminals mind and if the criminal thinks of an illegal act the collar will shock them and fly them home. There will be no more cars that run on diesel but cars that generate power from the sun they will not fly or hover but they will be normal cars, there will also be hover bikes these are motorcycles that can hover so that the bike driver can't cause accidents on the road.
