The bit and the Planck scale should not be treated as rival candidates for the single foundation of reality. The it from bit or bit from it nonsense. A bit belongs to an informational logic of distinction, while the Planck scale belongs to a physical logic of measurement and limit. These may be connected, but neither clearly eliminates the other. Reality appears to be layered: lower levels provide the substrate conditions for higher levels, while higher levels organize, constrain, and interpret lower-level possibilities. The important thing may not be which layer is “really fundamental,” but how stable interfaces allow one layer of order to be instantiated in another.
This is visible in biology. Chemical reactions become biological when they are organized into systems that preserve boundaries, regulate internal conditions, repair themselves, metabolize energy, and maintain homeostasis. The organism is physically instantiated, but the biological level introduces its own logic: function, survival, adaptation, and self-maintenance. Likewise, chess is physically instantiated in pieces, and Spotify is physically instantiated in circuits, but neither is fully explained by the material substrate alone. The important thing may not be which layer is “really fundamental,” but how stable interfaces allow one layer of order to become operative within another.
Just as chess is not reducible to wood and software is not reducible to electrons, information and physics may be distinct but mutually necessary descriptions of the same structured reality.
Reality is not made first of things. It is made of relations that stabilize into things. At one level, those relations appear as space, matter, and fields. At another, as chemistry. At another, as life. At another, as consciousness. The brain is what consciousness looks like from the outside. Consciousness is what certain integrated living information-structures are from the inside.
