-Maybe every problem can be translated to geometry (use any shapes and -as many dimensions as you need).

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. +Lots of problems can be translated to geometry (use any shapes and as +many dimensions as you need).

- -
layer 3
key/value storage. Keys are content hashes. Values are -arbitrary but limited size content byte arrays. This -layer effectively implements content addressable -storage. Content addressible storage enables GIT-like -behavior (possibility for competing branches, retaining -history, transparent deduplication) -
