Actually, modern ICs are surprisingly regular and clean looking. My wife is a semiconductor process engineer and I occasionally get to peek at the electron microscopy images over her shoulder. She isn't allowed to tell me what they are, but I can read the distance scale, and these are transistor-sized features. And they have square corners and straight lines. It's pretty amazing stuff.

But yeah, if this thing wasn't produced by photolithography, it's sort of a evolutionary dead end. Whatever the semantics of what qualifies for an IC, this really isn't a meaningful predecessor of a modern chip.
