The present being as it is, we turn to the past for solutions in some areas, while the future is decidedly close at hand in others. WolframAlpha, the latest computational knowledge engine's goal is to make all the systematic knowledge immediately computable and accessible to all.
The quest to make knowledge computable has a long and distinguished history. Indeed, when computers were first imagined, it was almost taken for granted that they would eventually have the kinds of question-answering capabilities that we now begin to see in WolframAlpha.Try a few queries yourself, e.g., in the area of money & finance. Surprisingly, the answer to deeper questions is not necessarily 42.
PS By the way, there are many other interesting things to see and read and play with from Wolfram Research, developers of Mathematica, available on the Web.
