Of interest may be Simon's correspondence with computer scientist Joseph Weizenbaum, who objected to artificial intelligence programming on the grounds that it was half-sham, and as well an assault on human dignity; and with author Pamela McCorduck, commenting on her book on artificial intelligence, Machines Who Think.
