+Maybe every problem can be translated to geometry (use any shapes and
+as many dimensions as you need). Solution(s) to such problems would
+then appear as relatively simple search/comparison/lookup results. As
+a bonus, such geometrical *data storage* AND *computation* can be
+naturally made in *parallel* and *distributed*. That's what neurons in
+the brain appear to be doing ! :) . Learning means building/updating
+the model (the hard part). Question answering is making (relatively
+simple) lookups (geometrical queries) against the model.
