I think everything is going to change.In fact, everyday we hear something new is coming up of technology,so now I can imagine that people can fly by using clothing or anything else.Also English language will be the global language and maybe some countries will lose their native language.Many cities will have lots of incredible buildings and I expect that there will not be old buildings.In addition,maybe there will be wars but it is going to be different than now because of technology,but i hope there is no war anymore.
