It is doubling now every two years. Doubling every two years means multiplying by 1,000 in 20 years. At that rate we'll meet 100 percent of our energy needs in 20 years.

We'll be able to have very intelligent, little robots with computers going inside our bloodstream, keeping us healthy from inside, destroying cancer at the level of one cell.

Take death for example. A great deal of our effort goes into avoiding it. We make extraordinary efforts to delay it, and often consider its intrusion a tragic event. Yet we'd find it hard to live without it. Death gives meaning to our lives. It gives importance and value to time. Time would become meaningless if there were too much of it.

Death is a great tragedy…a profound loss…I don’t accept it…I think people are kidding themselves when they say they are comfortable with death.

Time would become meaningless if there were too much of it.

My view is that consciousness, the seat of "personalness," is the ultimate reality, and is also scientifically impenetrable. In other words, there is no scientific test one can postulate that would definitively prove its existence in another entity. We assume that other biological human persons, at least those who are at least acting conscious, are indeed conscious. But this too is an assumption, and this shared human consensus breaks down when we go beyond human experience (e.g., the debate on animal consciousness, and by extension animal rights).

I consider myself an inventor, entrepreneur, and author.
