The article rationalizes with physics, arguing that a physically large data store, when it is efficiently implemented, is limited by the inverse-square of distance inherent in a 3D world. Certainly there are exceptions when you make a system more efficient (for example, filling empty memory slots or moving systems closer together or paying for a better interconnect).
