There’s an interesting discussion of Complex Specified Information going on at the Uncommon Descent site. MathGrrl, a skeptic of ID, had started the discussion in an earlier thread and in a thread at Mark Frank’s blog. And now the UD staff have invited MathGrrl to author a guest post. The thread, and subsequent discussion, is an attempt to come up with an actually usable definition of CSI.
My own view is that CSI is pretty much vaporware – something with a name, but which cannot be pinned down. (Vaporware is a computer jargon term for announced software that does not exist.) Thus far, I see the discussion of CSI as consistent with my view. But it is an interesting discussion. I suggest that you read it for yourself and form your own judgment.
