AI

Every aspect of a person could be sampled, scaled, and extrapolated by AI. Not just voice, features, movement, but also personality and way of thinking. In other words, there could be multiple automated versions of you interacting with the world and acting on your behalf.

AI would then start adapting these avatars as characters encountering generated digital scenarios, either as entertainment in a game, or for gathering data from the interactions and outcomes.

The philosophical questions posed in sci-fi are: What if the avatars were sentient? What if you are actually such an avatar experiencing a scenario? How do you know reality isn’t a single player game and everything you experience isn’t a computer simulation?

The answer is we don’t conceptually understand the nature of reality and maybe it would spoil the point if we did.
