You seemed to hold the following views:
(1) Bostrom is drastically underestimating computational requirements, and
thus his simulation argument is incorrect.
(2) For ethical reasons, posthuman civilizations will probably refrain from
running ancestor simulations, and thus Bostrom's simulation argument is
A comment on view (2):
I don't think that Bostrom argued that posthuman civilizations necessarily
would run ancestor simulations. Rather, he argued that if we reach a
posthuman stage, and _if_ we end up running ancestor simulations, then it
is likely that we are currently living in a simulation.
Thus (2) is not a counterargument against Bostrom, but a counterargument
against a view not presented by Bostrom in "Are You Living In a Computer
It is quite possible that no complete ancestor simulations will be run in a
posthuman future. The Sysop Scenario is such a case, if a Sysop wouldn't
allow individuals to torment sentients in Holocaust simulations etc.

You present no grounds for this suggestion, and I don't see why Bostrom
would be wrong in assuming that the computing power needed for the process
of selecting what to simulate precisely and what to "fudge" would be rather
