A favorite theme of mine is that the pace of change is accelerating quite dramatically. Even though I know this is true, I'm still blown away by how fast and how far we've come, even in the last, oh, year, year and a half. The internet is making us smarter by orders of magnitude, by exponentially extending our capabilities.
This extraordinary 4 1/2 minute film is a dense and mind-blowing journey into the heart of what's happening. It's called The Machine is Us/ing Us, and it was made by one Michael Wesch, Assistant Professor of Cultural Anthropology at Kansas State University. I recommend you view it more than once.
I first saw this when BoingBoing linked to it a while back. Just the other day my friend Greg sent it along to me again, and my second viewing impressed me even more than the first. Thanks Greg!
The version I linked above it the "Final Version." The version just before this received almost 2 million hits. I think they're almost the same; this final version is just slightly cleaned up based on some user suggestions.
