Historically, the idea that you take something novel and you break it has been seen as the ultimate rejection of Enlightenment values, of progress, of civilization - because how could you possibly move forward if you break technology? I think that that misses the point, that if you introduce any kind of technology, what you're introducing is a new way of living and the consequences of that new way of living for people who were enmeshed in a different way of living need to be thought through.

I am kind of a sucker for democracy, so I do think that what kinds of citizens we have in our societies are more foundational than what kinds of governments we have, and that the responsibility for self-government is ultimately with us. But we also have learned through a couple thousand years of democracy that democracies are only as good as people's capacity to reflect on those questions.

I'm all in favor of being able to imagine new frontiers with the aid of technologies, but I want a more compassionate approach that also recognizes that every time you're talking about new frontiers, there will be certain kinds of costs attached. There will be people who don't quite understand how to handle email who will decide to have private servers and then not know how to excuse themselves when it may be something as simple-minded as they were a little too far along in their lives to really figure out how to go back and forth between two different accounts.

Climate change is there as a reminder that we can get richer and safer societies that are also consuming more and more to the point where the stability of Earth's systems is being challenged at potentially catastrophic levels. I don't think we can stop that. Just the very same worries I have about prediction on the positive progressive side - I mean, predictions that say we'll be great, we'll be fine - also apply to predictions that are too catastrophic. I'm not sure we get those predictions right either.

I want a society in which we don't throw things and people away with quite the abandon we do, especially people. This is why the idea of disruptive technologies is quite dangerous, because you ought to be asking ourselves, what exactly are we disrupting?

I'm trying to make people more alert that mere acceptance isn't a good enough indicator that something is ethical. You actually need to stop and think. Acceptance on the basis of ignorance or deceit is not the same thing as the acceptance on the basis of ongoing vigorous democratic debate.
