Idk but I’m reminded of the 2002 adaptation of The Time Machine. One of the great achievements of our civilization was an advanced AI with all of our collective knowledge that you could converse with. Feels like our AI tech is on track to get there by the time we start dying off en mass lol
There are quite a few wonderful stories about the AIs continuing after humans are gone. "For a Breath I Tarry" by Roger Zelazny, and the whole of the Cyberiad by Stanislaw Lem, are some great ones.
That being said one of the critical points of "For a Breath I Tarry" is that the machines are just doing what they're programmed to do, maintaining the infrastructure for no one and just sitting in their orbits keeping the power grid going and all, and are actively hostile to any effort to bring the humans back because that would make things complicated and isn't in their programming (since although superficially they can converse and act "intelligently," more so than humans, they can't really grasp the purpose of things.) Also, "With Folded Hands" by Jack Williamson is another perfectly realistic one.
"Slow Music" by James Tiptree / Alice Sheldon is another very very good story that's exactly like that. Very liminal you could say; lots of going around alone in a world that's all empty but still all well maintained and functional.
