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.

Technology has changed things, same as everywhere. But the economy has changed drastically. When Jamaica first won independence, our dollar was stronger than the U.S. dollar. Now ours is about 90 to one. That's had a big impact on crime and poverty.

I often get asked, 'Is the book dead?' It hasn't happened yet. It's different than music. Music was always meant to be pure sound - it started out as pure sound and now it's pure sound again. But books started out as things. Words on paper began as words on paper. The paperback book is the best technology to deliver that information to you.

We always said if we were going to target a millennial consumer, then we had to do it in their mother tongue, which is digital.

I would never judge anyone for going anywhere for money.
