Most of the intelligence out there must be artificial intelligence. We keep looking for critters like us living on a planet like ours, where in fact the majority of the intelligence out there is not biological. That would be my argument.

In archaeology, context is the basis of many discoveries that are imputed to the deliberate workings of intelligence. If I find a rock chipped in such a way as to give it a sharp edge, and the discovery is made in a cave, I am seduced into ascribing this to tool use by distant, fetid and furry ancestors.

Our brains are continuing to evolve, and perhaps a few tens of thousands of years from now, our descendants will walk around with five pound brains, allowing them insights that we can't imagine.

While it may be disappointing, I have to confess to people who ask for my insights on the meaning of it all that astronomy doesn't provide any clearly useful data on matters of sin and souls.

Every time there is a major shift in technology, it's been hugely exciting and scary at the same time. I have seen some really drastic changes in technology, like shooting only film to video to digital.

By 2007, we were finally living in a culture where people get what networks are and what technology can do to connect people.

Technology has grown so much that there's a whole idea of gluttony. Sometimes you get carried away because you can have a camera go through the window, but do I need a camera go through the window? Those choices are up to the director.

One of the biggest challenges to medicine is the incorporation of information technology in our practices.
