I suppose it shouldn’t be surprising that we humans use evenly spaced gridlike formations in our technologies; our bodies are full of such structures.
Evenly spaced pixels (of a biological kind) means that’s how we’ll view the world; and our technologies will reflect how we process the world and they do. If you look at TV/computer screens for example, or voxels in immersive games; it’s not the same as what we have biologically but the notion of gridlike volumes for spatial navigation is our WE operate and so how we communicate to each other and interpret reality for our human needs.
