I think you’re on the right track. There’ll be a lot of personal-identity assumptions re-evaluated over the next generation as we see more interpenetration of personal parts as we start to offload cognitive capacity to shared resources on the internet.
Semi-related: I did my philosophy masters sub-thesis [15 years ago, not all opinions expressed therein are ones I would necessarily agree with now] on personal identity and the many-world interpretation of quantum physics. Summary: personal identity is spread/shared along all indistinguishable multiversal branches: indeterminacy is a feature of not knowing which branch you’re on. Personal identity across possible worlds may be non-commutative: A=B, B=C, but A≠C.
Survey completed. I’ve just checked the answer to the calibration question, and I’m glad I gave myself a low confidence score...
