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.

We now have powerful technology, which allows us a voice across boundaries, which was unimaginable at the time of the Greenham Protest, a protest that pre-dates the Internet and the mobile phone.

We're living in an age where we should be collaborating. Because it's the Internet now. It's hard to say who owns what.

Just let me use the technology I want at a fair price.

Perhaps the most important thing that technology does is free the listener to participate in ways that in all previous periods of listening were governed by the performer.
