‎By 2100, our destiny is to become like the gods we once worshipped and feared. But our tools will not be magic wands and potions but the science of computers, nanotechnology, artificial intelligence, biotechnology, and most of all, the quantum theory.

There are so many wonders awaiting us. If we can upload memories, then we might be able to combat Alzheimers, as well as create a brain-net of memories and emotions to replace the internet, which would revolutionize entertainment, the economy, and our way of life. Maybe even to help us live forever, and send consciousness into outer space.

Today's clunky smart glasses will be replaced by smart contact lenses. We'll command them by voice, blinking, or even thinking, to interact visually in 3-D with the Internet.

Scientists who have dedicated their lives to building machines that think, feel that it's only a matter of time before some form of consciousness is captured in the laboratory.

I had two passions when I was a child. First was to learn about Einstein's theory and help to complete his dream of a unified theory of everything. That's my day job. I work in something called string theory. I'm one of the founders of the subject. We hope to complete Einstein's dream of a theory of everything.

Even if we mortgage the next 100 years of generations of human beings, we would not have enough energy to build a Death Star.

Scientists willing to risk their reputations on higher dimensions soon found themselves ridiculed by the scientific community. Higher-dimensional space became the last refuge for mystics, cranks, and charlatans.
