It is difficult to define AI, because some people conflate it with AGI. In terms of social networking software, people are aided by programs that enable structured interactions using the worldwide web.
Frankly, it is now in a rather primitive state in comparison to how sophisticated it will become in the next couple of decades considering technology is improving at an exponential rate.
As an analogy, it is difficult to define a cyborg, since some people conflate it with a fictional or hypothetical person whose physical abilities are extended beyond normal human limitations by mechanical elements built into the body. In terms of mechanical elements extending our abilities beyond unaugmented, it is said that a person with a smartphone is about 10,000 times smarter than one without one.
Frankly, it is now in a rather primitive state in comparison to how sophisticated it will become. As mechanical elements migrate into our bodies we will see amazing things like the synthetic neocortex extender, that Kurzweil, lead developer at Google, has predicted will emerge in about 15 years.
