Mobile phones are misnamed. They should be called gateways to human knowledge.

People talk philosophically, Oh, I don't want to live past 100.' You know, I'd like to hear them say that when they're 99.

We have the means right now to live long enough to live forever. Existing knowledge can be aggressively applied to dramatically slow down aging processes so we can still be in vital health when the more radical life-extending therapies from biotechnology and nanotechnology become available. But most baby boomers won't make it because they are unaware of the accelerating aging process in their bodies and the opportunity to intervene.

Death gives meaning to our lives. It gives importance and value to time. Time would become meaningless if there were too much of it.

The telephone is virtual reality in that you can meet with someone as if you are together, at least for the auditory sense.

A lot of movies about artificial intelligence envision that AIs will be very intelligent but missing some key emotional qualities of humans and therefore turn out to be very dangerous.

Those with engineering skills will build tomorrow's genius computers. But those with the ability to create knowledge of any kind will be the ones who are best able to extract great value from them. The way to create value in the age of genius machines will be to compile and disseminate knowledge that other people will find useful.
