When I was a student at MIT, we all shared one computer and it took up a whole building. The computer in your cell phone today is a million times cheaper and a thousand times more powerful. What now fits in your pocket 25 years from now will fit into a blood cell and will again be millions of times more cost effective.

Although I'm not prepared to move up my prediction of a computer passing the Turing test by 2029, the progress that has been achieved in systems like Watson should give anyone substantial confidence that the advent of Turing-level AI is close at hand. If one were to create a version of Watson that was optimized for the Turing test, it would probably come pretty close.

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

Nature, and the natural human condition, generates tremendous suffering. We have the means to overcome that, and we should deploy it.

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

Find your passion, learn how to add value to it, and commit to a lifetime of learning.

There are downsides to every technology. Fire kept us warm, but also burned down our villages.
