I haven't read science fiction in a while. I used to be way into dystopias (Zamjatin, Huxley, Orwell, and Bradbury), but recently I've become very fascinated in Olaf Stapledon's "Last and First Men" (1930) because someone from my university department wrote a BA thesis on the recent (2020) film adaption with Tilda Swinton. Facing the cosmic conclusion of humanity, our distant relatives from the far far future reach back to us, the first race of humans, and tell the story of what awaits us ahead.
I haven't yet read the book - just today grabbed it from the Internet Archive and scraped together the 400 academic publications that mention it (through JSTOR, EBSCO, and dimensions.ai). It's going to be my this summer's book - I'm going to take it slow, enjoy our future history, and study the work's impact on later science fiction (it is supposedly one of Orwell's hidden sources), i.e. the bits of it that made it into Futurama, for example. From what I've seen and read about it thus far, it's going to be a great read.
