There are also two types of distopian:

• Post apocalyptic (mad max, terminator, etc)
• Evolved society (brave new world, minority report, etc)

Both have occurred in our history many times – the fall of the Eastern Roman Empire and the ushering in of the dark ages, as well as several mass extinction events (Black Death in Europe, Small Pox amongst Native Americans), etc.

The end is definitely coming (again), but each time some of us around to pick up the pieces and move forward!
