IBM computer proves formidable against 2 human debaters

An argumentative computer proved formidable against two human debaters as IBM gave its first public demonstration of new artificial intelligence technology it's been working on for more than five years. The computer made its case for government-subsidized space research by pulling in evidence from its huge internal repository of newspapers, journals and other sources. After delivering opening arguments, the computer listened to a professional human debater's counter-argument and spent four minutes rebutting it.
