Steven J. Dick: Biological intelligence is the exception, not the rule

"Biologically based technological civilization...is a fleeting phenomenon limited to a few thousand years, and exists in the universe in the proportion of one thousand to one billion, so that only one in a million civilizations are biological." -- Steven J. Dick, NASA Chief Historian

In a post-biological universe, says Steven J Dick, machines are the dominant form of intelligence.

From the Daily Galaxy article:

This worldview of the cosmos as a biological universe is a revolutionary perspective as profound a revision in our way of thinking as the Copernican and Darwinian revolutions. It is a worldview that believes that "planetary systems are common, that life originates wherever conditions are favorable, and that evolution culminates with intelligence."
