All that reading is hard to do, can't I watch some outer limits episodes instead?
I have watched a lot of larry krauss on youtube, and maybe I am wrong, probably so, but he seems to be saying that within maybe 250 years we will have expanded as much as possible, that to expand anymore would require more resources than we could harvest from our entire solar system, much less planet earth. This was in context to information processing I believe. That seems very dim, only 250 years left? He talked about how the universe was forever expanding, it was not stable and not going to deflate back in on itself from some theories.
