In a computer games you usually experience lag on crowded places because, the game can not handle the exponentially growing amount of interactions between all the players on the a area. If you want to get quickly to the other side of such a crowd, the shortest way is not directly through. Does this sound familiar? Is it not how light particle behaves when bending on the gravity? So in a nutshell what do you think: does the gravity happen because the space is kind of lazy and shovels the ‘shut up and calculate’ to a dark hole?
No, that's just anthropomorphization. It's true that the number of interactions between particles goes up as the density rises, but if you think of space as a computational framework, then an area of low density is an area where more computations could be happening. Empty space is more like wasted computation. We don't know why gravity exists, just that it does.
