Have you ever watched larger scale simulations of things like galaxies crashing together or boats apsizing or weather patterns? I imagine it being something like that, our whole lives being incidental parts of the math necessary to display whatever it is someone's actually interested in on a screen we could no more perceive than a character from the Sims could.
If that's the case, the chance that we could ever get the attention of these engineers is infinitismally small, unless we start doing shit on the scale of like... galactic filaments.
Not that I have anything against filament-level gigaprojects
Gotta secure the local supercluster against those illegal aliens somehow.
