I haven’t thought very seriously about this for many years, but FWIW: I think quantum immortality only applies to your subjectivity, which itself isn’t terribly well-defined. QI is basically suggesting that you’ll just keep happening to find yourself in scenarios where you’re still around. It doesn’t say anything about in what condition you’ll still be around, or whether there will be others around along with you.
One weird move that I think would totally fit quantum immortality is if you shift your subjectively experienced identity to the AGI even as all of humanity, including your old body, dies.
