Part 5/9:
At first glance, it seems counterintuitive that a three-dimensional quantity would store less information according to the surface area. One might argue that as we add more hard drives to a designated volume, the capacity to store data increases cubically—something expected from classical thermodynamics. However, the pivotal realization is that upon increasing the scale sufficiently, the collection of hard drives would eventually undergo gravitational collapse, forming a black hole. This introduces a fundamental limit to information storage: as more information is added, it inevitably tends to be harnessed by black holes, reinforcing the idea proposed by Bekenstein that no object can exceed the black hole information limit.
