In a hundred years’ time, I expect the world to have changed beyond
recognition. In the
aftermath of a nuclear holocaust (which, in all probability, will have occurred
by the end of the 21st century) human society and human lifestyles will have
been mangled.
Currency will no doubt have become completely physical by the end of the
21st century. What's more, rather than the legal tender of pre-nuclear-war
countries, resources such as food and gasoline will have become de facto currencies during the nuclear
winter. Between permanent trading partners, however, the old paper currencies
could be a convenient commodity.
By the end of the 21st century, there will be no more food left from the
current globalized society. Everything of note will have
been scavenged so crops will need to be grown to maintain the population. Society
will have regressed to an agrarian one where the majority of the people work
the fields (the exceptions to this might be rare cases where a community has
enough stockpiled fuel, machinery and know-how to automate the process).
On the other hand, to the joy of traditionalists around the globe, in
the period shortly following nuclear war, family will have become extremely
important. While social bonds can be easily broken following a
nuclear apocalypse, family ties can be much more resilient, especially if the person
has no easy way of leaving. This creates a much more tight-knit home
environment despite the gloomy future.
While the future might look grim it is important to always look on the
bright side of life: in a post-apocalyptic society people are bound to pick up
useful skills to survive.
