Speaking of 3D chips. We live in 3D world but our chips are mostly 2D. Yeah I know there are layers but overall the chip is flat slab. If we wanted to simulate 2D world in hardware, we could do it very efficiently on our CPUs and it would be infinitely scalable (assuming the world interacts mostly locally). Here comes the interesting part: if we live in a simulation ran by higher-dimensional beings, we have to transform our physics into a form that would reveal some inherent dimension-ness of our physics, then if we find this number, the beings live in a world with one more dimension. So for example if our physics seems to be 10 dimensional, the beings live in 11 dimensional world and their CPUs are 10 dimensional. They designed our physics to be only 10 dimensional so that they can run it efficiently on their CPUs.
