Against this backdrop the seemingly unstoppable and ever accelerating cultural homogenization around the world brought about by travel, the internet and social networking, although often decried, is probably a good thing even if it means the loss of cultural diversity: it increases our sense of togetherness via the sense of a shared culture. In fact, breaking down of cultural barriers – unfashionable as this can sound – is probably one of the few things that societies can do to increase harmony among ever more heterogeneous peoples.
So, to my mind, there is little doubt that the next century is going to be a time of great uncertainty and upheaval as resources, money and space become ever more scarce. It is going to be a bumpy road with many setbacks and conflicts. But if there was ever a species that could tackle these challenges it is our own. It might be surprising, but our genes, in the form of our capacity for culture, have created in us a machine capable of greater cooperation, inventiveness and common good than any other on Earth. And of course it means you can always find a cappuccino just the way you like it no matter where we wake up.
