There are dangers, but only dangers if people don't understand where technology is taking us.

When we're born, we want to know why the stars shine. We want to know why the sun rises.

We need an enduring, robust theory of education. Now, it seems education careens from one fad to another and often back again. I think that with better education and students willing to put in the 10,000-hours to become expert, we could develop better science professionals, even theoretical physicists.

Our grandkids will lead the lives of the gods of mythology. Zeus could think and move objects around. We'll have that power. Venus had a perfect, timeless body. We'll have that, too. Pegasus was a flying horse. We'll be able to modify life in the future.

In the beginning God said, the four-dimensional divergence of an antisymmetric, second rank tensor equals zero, and there was light, and it was good. And on the seventh day he rested.

We physicists don't like to admit it, but some of us are closet science fiction fans. We hate to admit it because it sounds undignified. But when we were children, that's when we got interested in science, for a lot of us.

Growing new organs of the body as they wear out, extending the human lifespan? What's not to like?
