Dear Psychobabble, Sometime in the early 2000s, I came across an essay in which the author argued that no artificial consciousness will ever be believably human unless it can dream. I cannot remember who wrote it or where it was published, though I vividly recall where I was when I read it (the periodicals section of Barbara's Bookstore, Halsted Street, Chicago) and the general feel of that day (twilight, early spring).
