As a species, we will alter ourselves long before nature has a change to change us through evolution. Before the end of this century we will become one with our machines. We will remake ourselves in our own image. If we are not vigilant, we will become slaves or pets to our own creations as our machines far out pace our intellect and strength.
For good or evil, we will become our own thoughts. Let us hope we will be able to survive our own darkest natures.
