Well yes, I think that's a likely scenario. But it doesn't have anything to
do with the SA - it works exactly as well whether we're the
"original"/"real" pre-Singularity civilization or a simulation. It also
appears to agree with my position and contradict yours here:

About 10^11 galaxies, 10^22 stars - a large number by everyday standards,
but tiny compared to the size of the search space involved in the origin of
life let alone intelligence. (Bad side effect of spending too much time on
AI or anything else that - the known universe starts looking like a cosy
little garden. It just doesn't look big anymore :P)
But if you still think 10^22 is a big number in this context, why are you
happy to postulate that intelligence only happened once?
