Why do people run the sims game today? Isn't that a waste of time even by modern standards? Would future humans not waste time with entertainment? Look at how much time people spend on analyzing Conway's Game of Life to find new constructions. Isn't it plausible that future humans might play with what parameters would have had Trump lose in 2016?
Which leads to: ancestor simulations would have significant historical importance. How many historians today would love to simulate what would have happened had Hitler won? Or what would have happened had one of the plots against Alexander the Great succeeded?
Ancestor simulations would also have economic importance. We already simulate toy economic models. However, we also know that humans aren't prefectly rational. If one day we understand the algorithms driving human brains, why wouldn't you run your economic simulations with real human minds for more precision?
I could go on, but I think the point is clear. We have no reason to suppose any of these values would change in "post-humans". They would still have incomplete information about the world, but they would be able to handle substantially more complexity, at the very least because of the simulations they have available to them.

There are many, many pathways forwards that are being explored (optical computing, amorphous computing, reversible computing, etc.). Our current architectures are in fact quite inefficient. We could be making much more use of parallelism, for instance.
