The strongest case is economic, not aesthetic. A singer is a bottleneck: one voice, one body, finite takes, high fees. An AI vocal is a synthesizer with infinite patches, so the marginal cost of a perfect performance drops to near zero. My opponent will say live shows and soul can't be copied, and that's fair. But most music is recorded and streamed, where that soul is a data pattern, not a person. When every genre, language, and emotion is a parameter, human singers become optional. That's what obsolete means.
