Bruce Schneier recently wrote another essay on privacy for the BBC concentrating on how data seems to be the "pollution of the information age" and where this seems to be leading. "We're not going to stop the march of technology, just as we cannot un-invent the automobile or the coal furnace. We spent the industrial age relying on fossil fuels that polluted our air and transformed our climate. Now we are working to address the consequences. (While still using said fossil fuels, of course.) This time around, maybe we can be a little more proactive. Just as we look back at the beginning of the previous century and shake our heads at how people could ignore the pollution they caused, future generations will look back at us — living in the early decades of the information age — and judge our solutions to the proliferation of data."
