What do you predict the future will be in 50 years?

In 50 years I think that there will be big changes, the world won't be the same as today. The future will be better. In my mind the future will be great I'm sure that everyday life will be so easy. There will be smart houses and we'll be able to open them without keys just with our voices. There will be Hi-tech schools. There won't be any gasoline-powered automobiles, there will be just electric cars or maybe self-driving cars but for flying cars I think that we're way too far from realising it. Also the new technologies will be able to eradicate all the diseases, and people will eat more healthier so they can survive longer. Moreover I think that technology will help to solve most global issues. Perhaps there will be robots which will replace humans. And why not, maybe the future will allow us to colonize the Moon or an other planet and we'll discover a new planet where a new species of lives is living. Perhaps people will be able to communicate without talking. Well that's my own idea about what the future will be in 50 years.
