If someone living in 1875 would have tried to imagine what the world may look like a century later, in 1975, it would have been challenging, but not difficult. Many progressive minds would have predicted faster economic development, scientific achievements, new medicines to combat deadly diseases, end of slavery, de-colonisation and advent of human rights. However, if someone in 1975 would have attempted to guess what the world would look like just half a century later—in 2025—that would have been much more difficult. If the life of our grandparents was very similar to the life of their grandparents (often they would live in the same city and even do the same jobs), no babies born today would be doing their grandparents’ jobs, or living in the same towns.
