The purest case of an intelligence explosion would be an Artificial Intelligence rewriting its own source code. The key idea is that if you can improve intelligence even a little, the process accelerates. It's a tipping point. Like trying to balance a pen on one end - as soon as it tilts even a little, it quickly falls the rest of the way.

By far, the greatest danger of Artificial Intelligence is that people conclude too early that they understand it.

Anything that could give rise to smarter-than-human intelligence - in the form of Artificial Intelligence, brain-computer interfaces, or neuroscience-based human intelligence enhancement - wins hands down beyond contest as doing the most to change the world. Nothing else is even in the same league.

There's a popular concept of 'intelligence' as book smarts, like calculus or chess, as opposed to, say, social skills. So people say that 'it takes more than intelligence to succeed in human society.' But social skills reside in the brain, not the kidneys.

When I finished 'P.S. I Still Love You,' I truly was done with the series. I kept saying the books were two halves of a heart. But I suppose time and space had made me nostalgic, because my mind kept drifting back to Lara Jean and Peter, wondering what they were up to.

By 30, I was separated from my husband, and I clearly remember sitting in my lovely office with a magnificent view, staring at a very lucrative pay stub, and bursting into tears because I was just miserable. So I had to make a decision: Keep following my plan, or be honest with myself and search for my true passion.

I could never be with a married man. I just can't. I could never imagine myself being the mistress of somebody.

When I was growing up, I always read horror books, while my sister read romance novels. My sister became unmarried and pregnant during high school, and she kept saying, 'This wasn't supposed to happen! Why is this happening to me?' Someone should have given her another book to read.
