To build a giant lookup table. Google is a small giant lookup table, but we need a much, much bigger one.

Google is too much about interfacing with their table, but that should be put aside for the moment. What I want is to input any blob of data and output should be all possible relations this blob of data has with any other blob of data.

For example, if I input an integral (calculus), its solution (function) would be one of the natural outputs. If I input a picture, all pictures of the same object(s) is the natural answer this GLT should return. Then you can filter them further. It goes on and on. The table itself is constantly updated, of course.

The craziness of this idea is only in that I think it would soon replace Google. Otherwise it's quite basic.
