It is kinda difficult to predict what we'll have in our future. I have three possible versions. The first one is people's spaceflights, it may be everybody will be able to visit the moon, to travel around the Earth. We will have many intergalactic cafes and hotels. Anyway scientists try to create modern spaceships for long distances. The second is making new people with help of nanotechnology. To change some parts of a brain, to cure AIDS and cancer and what not, we will live much more longer than we do. The third is cleaning water on the Earth. Just imagine people have a mortar and they can drip it onto bad polluted water and get the clean one. I see these wonderful technology in our future.
