Some people call this artificial intelligence, but the reality is this technology will enhance us. So instead of artificial intelligence, I think we'll augment our intelligence.

Think about when a digital business marries up with what I'll call 'digital intelligence.' It is the dawn of a new era about being a 'cognitive' business. When every product, every service, how you run your company can actually have a piece that learns and thinks as part of it, you will be a cognitive business.

Artificial intelligence is one of 50 things that Watson does. There is also machine learning, text-to-speech, speech-to-text, and different analytical engines - they're like little Lego bricks. You can put intelligence in any product or any process you have.

You build your own strategy. You don't define it by what another competitor is doing.

War on Everyone,' I think... the script was hilarious to me, but it's very dark, dark humor. It's super dark.

I'm grateful to songwriting and recovery to bringing me to a place of peace.

I think, technically, we have won the war because people are going back into their neighbourhoods. Boko Haram as an organised fighting force - I assure you that we have dealt with them.

I love painting and music, of course. I don't know nearly as much about them as I know about poetry. I've certainly been influenced by fiction. I was overwhelmed by War and Peace when I read it, and I didn't read it until I was in my late 20s.
