How a universe achieves immortality. What happens when a computational universe copies itself — and why it might not need a reason to do so. The final essay in the trilogy.

Why the deepest crisis in physics might be a category error. What happens when you try to reverse-engineer a rendering engine from inside it: the unification crisis looks like an abstraction-layer mismatch.

Why the universe might be a map built by the civilization trapped inside it. The simulation argument has a motivation problem — and the most plausible reason to build a universe-scale simulation is navigation.
