You can soup up a local 3d torus with a small network
like connectivity. That keeps the the node connectivity
and number of wires still manageable.

Moreover, the universe does it with local connectivity
(even quantum entanglement needss a relativistic channel
to tell it from RNG) just fine. A 3d grid/torus would
be a good match for anything that can do long-range
by iterating short-range interactions.
