Computers are increasingly competing against humans to see whether man or machine is smarter. In the latest demonstration of artificial intelligence or AI, a computer went up against humans in live, public debates. The debates held this week in San Francisco provided a new example of how computers are fast improving to think and sound more like humans. The event was a demonstration of an AI system developed by major technology company IBM. It is called Project Debater. IBM said it was the first time ever that an AI system has competed in a live, public debate with humans.
