In 2040, there will be highly developed technologies. The smart house itself will bring itself in order, robots will perform heavy and unpleasant works instead of people. Each person will have a small aircraft with which to move, so there will be freer streets. Clothing and other things will be made from a second-hand raw material. Oil and gas will be replaced by other energies. The problems of the thermal effect will be solved, the climate will begin to normalize. All wars and conflicts between states will be completed, peace and harmony will reign everywhere.
