The main question that I'm asking myself is, what is the meaning of technology in our lives? What place does technology have in the universe? What place does it have in the human condition? And what place should it play in my own personal life? Technology as a whole system, or what I call the technium, seems to be a dominant force in the culture. Indeed at times it seems to be the only force - the only lasting force - in culture. If that's so, then what can we expect from this force, what governs it? Sadly we don't even have a good theory about technology.
I'm trying to investigate ways to understand the long-term consequences of technology in the world and place it into some position along with other grand things like biological nature, big history, the physics of the cosmos, and the future. It's a very ambitious project and, surprisingly, there isn't really much thinking about technology in terms of its sphere of influence in a way that might be useful to thinking about how to evaluate what we make.
