Implications for artificial intelligence
Philosopher John Searle argues that Watson—despite impressive capabilities—could not actually think. Drawing on his Chinese room thought experiment, Searle claims that Watson, like other computational machines, is only capable of manipulating symbols, but has no ability to understand the meaning of those symbols; however, Searle's experiment may be flawed.

While Watson is a high-performance analytics system, it is not as cognitive as human beings (it cannot think like human brain but can only learn, synthesize and provide an ouput). Another research project at IBM that focuses on cognitive computing, which is funded by NASA, aims at simulating the fundamental behaviour of human brain which is to process information and respond on event-driven basis instead of a clock-driven basis. The researchers of this project on December 2011 explained that they might be able to combine their accompolishments in making a cognitive computer with Watson's analytics ability (like combining brain's left hemisphere with right hemisphere) to produce a more sophisticated cognitive computer. But they agree that exactly simulating a human brain is not possible as yet, because the brain itself is unknown to man.
