"Many quantum physics are realizing or hypothesizing that consciousness is not a byproduct of evolution as has been suggested. Or for that matter, an expression of our brains, although it expresses itself through our brains. But consciousness is the common ground of existence that ultimately differentiates into space, time, energy, information and matter. And the same consciousness is responsible for our thoughts, for our emotions and feelings, for our behaviors, for our personal relationships, for our social interactions, for the environments that we find ourselves in, and for our biology."

The greatest existential risks over the coming decades or century arise from certain, anticipated technological breakthroughs that we might make in particular, machine super intelligence, nanotechnology and synthetic biology. Each of these has an enormous potential for improving the human condition by helping cure disease, poverty, etc. But one could imagine them being misused, used to create powerful weapon systems, or even some kind of accidental destructive scenario, where we suddenly are in possession of some technology that's far more powerful than we are able to control or use wisely.
