Fidelity Explained in Westworld
Short Answer
Fidelity is Westworld's measure of whether a copied mind can reproduce the original person inside a host body.
The Delos project tries to make immortality technical: if a copy acts like the original under stress, it may be considered faithful. The repeated James Delos failures show how unstable that dream is.
Fidelity does not answer whether a copy deserves moral status. Westworld uses it to ask whether identity is pattern, memory, body, choice, or something no test can fully prove.
