It seems to me that the questions we're asking in the 2010s seem to be less about "how can we make a new technology" and more about "how can we use the technology we already have". We already have pretty much all the computing power we need for most tasks* at our fingertips, and the question is now what do we do with it? It's the same for other technologies. How do we use, say, social networking, or databases, or what have you in a way that people want to use and that we can profit from?
