I'm on my first reread. Despite some pacing problems, I really enjoy the feelings of hope hpmor inspires in me. That humanity can conquer death and overcome our problems, and that in the far future our ascendants will look back on the struggles we faced here in our cradle with wonder. I have never found another work like it. Maybe hn can recommend me something?
The author also has a long running web fiction about AI taking over the world. It is hilarious and provides a deep insight into modern religious cults.
