Yes, this is what I mean. Part of what makes it an effective filter might be that it's hard to detect. If it's a "black hole catastrophe in hadron collider" then its technologically much easier to build the collider than to realize that the collider will create a black hole. I've suggested that this kind of possibility should cause us to put lots of resources into looking for the ruins of dead alien civilizations.

The one possible way to argue against this grim perspective is to suggest that probability is distorted by simulation argument. If at least one super AI will be created it will create millions of simulations (to numerically solve Fermi paradox, e.g.) and it will overweight the number of real civilization. But will it save them from the said black hole?

Then the Fermi simulation paradox is "why is the universe so old?" If the universe gets quickly colonized then most of the simulations of civilizations that have not yet made contact with aliens will have universes much younger than ours.

They could put arbitrary timelines in the simulations. The fact that we see really old universe is an argument against future colonization by many species.

It could be the universe is only "old" by our standards. Maybe a few trillion years is a very young universe by normal standards, and it's only because we've been observing a simulation that it seems to be an "old" universe.

This is certainly possible. But if we are in a simulation of the base universe then it's strange that we experience the Fermi paradox given the universe's apparent age.
