Even if you hit roadblocks from time to time, the general cosmic-scale conversion of "dumb matter" to "computation capable matter" can only be... exponential. Imagine all matter in a planet the size of Earth converted to computing infrastructure, considering we're only living on a thin thin crust on it. When the evolution of intelligence goes beyond the stage of slowly evolving (if evolving at all) forms like humans, "life" will spread like a plague through the universe and its only purpose will be to convert all matter into "shit that can run the software that is we"... Any intelligence with a different purpose will simply be eaten alive but those with this one. Only the second law of thermodynamics can stop that, and even that only "works" the way we imagine in a finite universe (and despite out forced rationalization and intellectual masturbations our brightest were capable of, we have no reason to believe anything is anything but infinitely infinite, whatever that could even mean). And we can't even imagine how the evolution of information in infinite space and time could unfold, even with "local containment" via the "light speed limit"... An no, we are not unlikely to model anything such complicated, we are almost sure not to... Because "the children" will awake much sooner that this computational power will exist, probably doing the right thing of terminating bio-humanity as it's so (computationally) wasteful, and remnants of us will only endure in "historical entertainment simulations" thinggies... (And this is the optimistic scenario anyway, in which post-human life would retain some human-type characteristics by virtue of "descending" from us. If an alien superintelligence reaches Earth first it might not even care to analyze us well before restructuring matter for its own purpose, so paradoxically, developing superhuman-intelligence-that-will-terminate-bio-humans asap is probably "humanity's best bet" of "not being completely forgotten" / "transmitting our memes".)
