I have spent the last week as a nearly full-time reader of platypusology. - Stephen Jay Gould

We are, whatever our glories and accomplishments, a momentary cosmic accident that would never arise again if the tree of life could be replanted from seed and regrown under similar conditions.

Life is a ramifying bush with millions of branches, not a ladder. Darwinism is a theory of local adaptation to changing environments, not a tale of inevitable progress. “After long reflection,” Darwin wrote, “I cannot avoid the conviction that no innate tendency to progressive development exists.”
Jastrow might argue that he is only considering the single pathway through the immense labyrinth of life’s bush that happened to lead to us. Even here I might reply that while we have a personal motive for special interest in (and affection for) this particular pathway, we have no right to regard it (or any other) as the essential direction of life. The pathways leading to aardvarks, anchovies, or artichokes are just as long, intricate, and biologically informative.

Biological evolution is a theory about ties of physical genealogy based on reproduction with error and natural selection. Computers do not breed. Any direction imparted to biology by its Darwinian mechanism does not translate to pathways of industrial change; a biological past is no sure guide to a technological future.
