So, where are the robots? We've been told for 40 years already that they're coming soon. Very soon they'll be doing everything for us. They'll be cooking, cleaning, buying things, shopping, building. But they aren't here. Meanwhile, we have illegal immigrants doing all the work, but we don't have any robots.

If you gave kids peas that didn't look like peas and said they were a space shuttle, they're much more apt to eat them because it's now playtime.

The only way to make something cheaply today is to have it mass-produced. For example, you wear the same shoes as everyone else. If you had a fabber, you could custom-make shoes that perfectly fit your feet. Three-dimensional printing will help us move away from the mass consumption that is so deeply ingrained in our culture.

We tend to think of science as finding equations, like E=MC2, that are simple and elegant. But maybe some theories are complicated, and we can only find the simple ones.

A number of countries, including Russia and China, have put forward proposals to regulate aspects of the Internet like 'crime' and 'security' that are currently unregulated at the global level due to lack of international consensus over what those terms actually mean or over how to balance enforcement with the protection of citizens' rights.

Nowadays, social media is the easiest place to go to find something.

A lot of people think technology is a solution, but it's really just a canvas for your work. It can make good things amazing and bad things terrible. Facebook allows you to have access to mass audience really quickly if you do creative really well.

The United States invented the Internet and it has been our gift to the world, paid for by our taxpayers. The U.N.'s desire to take that gift as a means of increasing its power must be stopped.
