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

Inventing is a lot like surfing: you have to anticipate and catch the wave at just the right moment.

There is one brain organ that is optimised for understanding and articulating logical processes and that is the outer layer of the brain, called the cerebral cortex. Unlike the rest of the brain, this relatively recent evolutionary development is rather flat, only about 0.32 cm (0.12 in) thick and includes a mere 6 million neurons. This elaborately folded organ provides us with what little competence we do possess for understanding what we do and who we do it.

Launching a breakthrough idea is like shooting skeet. People's needs change, so you must aim well ahead of the target to hit it.

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.

We appear to be programmed with the idea that there are 'things' outside of our self, and some are conscious, and some are not.

I consider myself an inventor, entrepreneur, and author.
