There's this recent cool SF novel by the Polish (and undertranslated!!!) SF author Jacek Dukaj called 'The Old Axolotl'. In it, people used gaming systems to copy their 'beings' into machines before a planetwide wipeout event of biologic life. The machines, with the human simulacra within them, survive for hundreds of years. What's interesting about the books is that the machines feel human and have all the human emotions, but somewhat foreshadowing LLMs, they cannot learn like humans learn. The robot society is essentially stale, forever, nobody develops. (at least that's my interpretation as to why the robots fail in the book)
