My inelegant attempt to capture Stapledon's "Last and First Men" and "Star Maker" in a Tweet.https://twitter.com/michael_nielsen/status/1077389803711168512 …
I hope you do! Despite many, many flaws in some ways those books are the best science fiction ever written. I wish more people would pick up Stapledon's baton and run with it. (The modern-ish thing which feels closest, to me, might well be Carl Sagan's non-fiction "Cosmos".)
