Direct neural interfacing is an advanced technology used by the Concordiat, which directly links a human to an AI.

The Concordiat military used it its late generation warships during the Last War , as well as the Mark XXXII and XXXIII Bolos (some older units were retrofitted with the equipment). Therefore the crews of those awesome war machines could think and react as fast as their vessels: hyper-heuristic mode. Information could be directly 'uploaded' into the users mind.

While it provided a near-perfect combination of Bolo logic and precision with Human intutition and flexibility, the DNI could be addictive. It may also have had a small factor in the savagery of the Last War, with Bolo-Human partnerships fusing Bolo determination with human bloodlust into a terrible desire for vengeance upon the Melconians.
