Many people wonder what life will be like in 50 years time. No one can know for sure, but there are certain forecasts about world demographics, weather conditions, technology development, spaceflights, etc. In my opinion, it’s going to be the era of various machines, the so-called robots. They will be everywhere around. It will include self-operated vehicles, home-based robots, automatic workers, computer-based education and many other modern facilities. At the moment many countries spend millions to explore other planets and to make sure they contain appropriate living conditions. So, perhaps, in 50 years time people will be able to visit other planets in spaceships. It will become a popular type of tourism. Moreover, people will be able to purchase lands and build houses on some planets. Today it might sound as an absurd, but who knows how the things will change in the future.
