Currently, digital resurrection relies on artifacts such as photographs of a person, their correspondence, or voice recordings. But in the future, when whole brain emulation becomes possible, we will have a far more comprehensive source of information about a deceased person than ever before.
Based on the theory of mind, each of us has a “simulation” of important people in our brains. We will be able to extract these simulations from the WBEs of various people who knew the deceased and analyze cross-referenced memories to avoid confabulations. For example, using Bayesian Truth Serum.
In short, this is a great way to get the most useful and accurate information about a person in the [very] relatively near future.
Great, looking forward to it.
