Sparrow et al. originally claimed that reliance on computers is a form of transactive memory, because people share information easily, forget what they think will be available later, and remember the location of information better than the information itself. They posited that people and their computers are becoming "interconnected systems"; the same underlying processes used in traditional transactive memory to learn who in our social networks know what, is also being extended to encompass what a computer knows and how to find it.[4]
