Deciding which technologies to support for teaching and learning—and how to support them—depends, first, on our ability to learn about each emerging development. Selecting a platform without knowing what is coming right behind it can be risky. Similarly, it is folly to grasp onto a technology without seeing the variety of ways that the technology can actually be used.
But trying to grapple with what comes next is a deep problem. Doing so is partly a matter of science fiction, which consists, after all, of the stories we tell about the future. Doing so is also an issue of complexity, since each practice, or device, or network, or application comes embedded in a nest of other practices, or devices, or networks, or applications. Emerging technologies are a matter not only of qualitative challenge but also of sheer quantitative overload. Web 2.0, gaming, wireless and mobile devices, virtual worlds, even Web 3.0 in all its unrealized potential—each churns out new developments daily and connects with other domains to ramp up the problem still further.
