Why would it be coded to produce almost but not quite perfect results,
if the computing power for perfect results were available? (One could
fall back on "we don't know anything about the entity that wrote the
code", but such an agnostic position is hard to reconcile with any
conclusion other than "we don't know whether we're in a simulation" -
which is indeed the conclusion I hold.)<br>

But "much less than 10^10^89" and "much more than 10^10^89" are much
bigger targets than "just about exactly 10^10^89", and my argument
requires only those three categories.<br>
