I think we will always fill up the storage available as we crank up the fidelity of our recordings (simulations). Video is an approximation of reality, and we can always ramp up the resolution, ramp up the dimensions, always striving to simulate the universe at the same fidelity as the universe itself, to the point that the map becomes the territory itself. In other words, until it's no longer approximating, no longer compressing. There will never be enough storage to store our simulations of our reality as long as we're forced to use that same reality to construct the storage.
