We are headed toward 'perfect capitalism,' when the laws of supply and demand become exact, because everyone knows everything about a product, service or customer. We will know precisely where the supply curve meets the demand curve, which will make the marketplace vastly more efficient.

I think the 'Terminator' idea is a reasonable one - that is that one day the Internet becomes self-aware and simply says that humans are in the way. After all, if you meet an ant hill and you're making a 10-lane super highway, you just pave over the ants. It's not that you don't like the ants, it's not that you hate ants; they are just in the way.

Democracies are slow to anger and hesitant to go to war: Voters don't want to sacrifice their children for the glory of a selfish king.

Why commit technological suicide by restricting the flow of talent into the United States?

A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.

The quest for a quantum gravity is one of the greatest unsolved problems in all of science.

In the future, the Internet might become a 'brain net' where we send memories, feelings and sensations.

It's inevitable that we'll have some form of designer children, fueled not just by the science but by parents' hard-wired desire to give their children every advantage.

Until computers and robots make quantum advances, they basically remain adding machines: capable only of doing things in which all the variables are controlled and predictable.

I predict that technology will enable people to transmit their neuronal, actual feelings over the Internet.
