In fact, one reason I am interested in developing things in virtual reality is that they're so fascinating. I can come up with problems that are harder than warfare to take up people's time.

If you listen first, and write later, then what you write will have had time to filter through your brain and you'll be in what you say. This is what makes you exist. If you are only a reflector of information, are you really there?

I think seeking perfection in human affairs is a perfect way to destroy them.

As information technology becomes millions of times more powerful, any particular use of it becomes correspondingly cheaper. Thus, it has become commonplace to expect online services (not just news, but 21st century treats like search or social networking) to be given for free, or rather, in exchange for acquiescence to being spied on.

I'm an advocate of human nature.

We already knew that kids learned computer technology more easily than adults, It is as if children were waiting all these centuries for someone to invent their native language.

I fear that we are beginning to design ourselves to suit digital models of us, and I worry about a leaching of empathy and humanity in that process.
