The producers have told us the 4th season will show a major blurring of the line between human and Cylon to the point that you won’t be sure what it means to be a Cylon. I am curious what people think that means, other than the colonials being constructed beings too. No “robots” in the sense you might think of them — but then the Cylons, who are biological enough to be able to breed with the colonials, are hardly “robots” either.
