There are two types of fear, the first is the fear created by personal survival. The second is the fear of change. We will throw out success and run away from things that are good for us to avoid change. We think we know and understand fear such as the serial killer, the nuclear bomb, or global warming. Our most common fears regarding survival are easy to understand because we can formulate solutions even if they would never work.
I can almost certainly assure you that in the next one hundred years you will long for the days when nuclear war seemed like a legitimate fear. Technology is moving off the screens and into our bodies and this is going to have profound implications. What will you do when you are told that all your accumulated experiences are irrelevant because in seconds you can become anything you want? You might think this is amazing but think of the implications. If you can become anything, who are you? If you choose not to act, you could find yourself scraping the bottom unable to compete with genetically improved humans. What if you were offered the ability to lose the capability to commit evil, would you accept it? If you accept it, would you still be you?
What we call science fiction is starting to fall behind what we are actually accomplishing. The biggest challenge we will have in the future will not be about weather or murderers, it will be about existence. We will try to escape it by chasing media and digital worlds but the gleam will wear off. When the gleam runs out you will be left to make very serious decisions that will have dramatic effects on your life over very short time frames.
Now, more than ever, we need to become architects of the future. We must face the coming challenges now, not once they arrive.
