That would violate a physical principle (The Holographic Principle[1]), namely that the amount of information in any given volume of space is limited by the volume's surface area. At some point an exponentially growing number of connections is going to overtake the surface area of the volume of space occupied by the supposed physical device. [1] I understand that this is largely theoretical, but it seems to be pretty much accepted by the Physics community AFAICT.
