The basic premise of the "singularity" is that we'll be unable to understand the technological changes happening around us. I think that's already more true than not.
Although we're pretty loathe to put any sort of implant into our brains (the sort of thing we'd all agree turns us into cyborgs!) there is little resistance to carrying a blackberry everywhere we go. I even sleep next to mine and wake up to its alarm every morning (and, according to my love sleeping next to me, I haven't lost my humanity yet.)
Was the quirky tendency of early man to carry shiny stones along with him a preparatory precursor to our future of carrying blackberries?
No, not by our standard definitions of cause and effect, but evolution is never the less tapping into such instincts; a plan is unnecessary.
We are essentially a cybernetic society already.
If you divorce yourself from the perspective of humanity as isolated individual bodies, and view us in the equally fair light of us being social cultures and shared infrastructure it's clear we've incorporated technology at every level.
Does that point even require support? I'm discussing this on the internet - a technology that might have passed for a god not long ago. The world's population has exploded, and the wealth and physical health of that population has increased dramatically. Future technologies are nearly unpredictable and setting limits on their possibility is difficult past 50 or 100 years.
And then think of the markets, the technological fields, the cultures of religion and entertainment fetish. All of these things are diversifying and evolving with explosive speed, while simultaneously deepening their scope. No one individual can keep up with all these things, and the society itself is a frothy storm of them, and still we go on with (what seems to be) happy success.
They say in the case of a true "singularity" (one around a black hole) that you'd not notice yourself passing over the edge of it. It's only the place where outside observers would lose track of you.
I'd imagine it's like the experience of a diver coming up slowly from a deep dive. You're forced to stop at various depths so that the compressed gasses can escape without giving you the bends. At those moments deep in the water it's sometimes easy to forget which way is up, but the real danger is being caught unknowingly in a current. The whole mass of deep water around you could be sucking you far away from your dive boat, and you simply have no way of knowing. Relative to your dive partner you haven't moved, but that's only because you're moving together.
If there's any lesson of the singularity, it's that considering the simpleminded scifi version of it is a good stepping stone to understanding society and our human experience more accurately in the present. Don't let the refutations of the simplistic versions of this idea blind you to the more complex and human realities that lie behind it.
We are awash in a see of evolving technology (both material and intellectual) that is thoroughly out of our individual control, and yet we are still a part of it and it is our moral prerogative to use it to the best of our abilities. Evolution has not stopped, we're just coming to realize it's never really been limited to DNA.
The incorporation of technology into society will continue. It's effect on morality and human nature will continue to accelerate. It's wise to be mindful.
As for practical applications of this philosophic mindset I can recommend a practical idea:
Social Networking (in it's myriad guises) is the "global brain" - act accordingly and use technology to amplify your ideas (and possibly reward your individual self.)
