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.

You don't support politicians in their elections if whoever's seeking money only has a goal to stay in office or get in office. You have to pick the people who are going to do the best job.

When people talk about conservative government, that's it in a nutshell. We're using taxpayers' money like we would use our own. We're holding in the reins during good times so we're prepared during bad times.

When you look at movies like 'Titanic,' they make money because of women. They go to see it and bring their men, too.
