I present the following addition to the discussion on space colonization
You may be interested in this thread and this post. (The latter doesn't talk about s-risk directly, but there's an obvious extension of it to s-risk.)
Excellent, thank you! Yes that is interesting to me. The only other place I saw the s-risk/aliens connection being made was in this paper: Risks of space colonization (Kovic, 2020), section 4.4.
I'll incorporate that along with your posts into my review.
"or more likely we are an early civilization in the universe (according to Robin Hanson’s “Grabby Aliens” model) so, 2) quite possibly there are no grabby aliens populating the universe with S-Risks yet"
But our model implies that there are in fact many aliens out there right now. Just not in our backward light cone.
