An excerpt from a book I bought recently

Interlude: The Investigator

—it reaches out it reaches out it reaches out it reaches out— One hundred and thirteen times a second, nothing answers and it reaches out. It is not conscious, though parts of it are. There are structures within it that were once separate organisms; aboriginal, evolved, and complex. It is designed to improvise, to use what is there and then move on. Good enough is good enough, and so the artifacts are ignored or adapted. The conscious parts try to make sense of the reaching out. Try to interpret it.
