I came for the rigorous, mathematically-informed hard sci-fi that came up with a solution to unify quantum mechanics and general relativity and also invented an entirely new system of physics. I stayed for the surprisingly human musings on what it means to be YOU in a world where you can live (and change) forever, and also the optimistic speculations about the future of humanity (or what we might become).

This is the sort of book you can read at a jazz bar while sipping on a dirty martini to cosplay as a pretentious asshole. It's also the sort of book that will blow your mind with ideas and thinkers both real and fabricated (doesn't quite feel like it actually matters either way though) and have you kicking your feet at puns like "chiropraxis" (the author literally lists a "pun consultant" in the acknowledgements). Not sure how I feel about the antinatalist turn at the very end, but for the most part I really enjoyed this. I understood Iain Hamilton Grant's introduction only marginally better (as in, like, slightly more than almost not at all) after finishing the book.
