Actually, the "virtual voice" technology is not AI. It's the same sort of text-to-speech system that's existed for decades, just in a more refined form. A considerable amount of time (money) and (human) effort was still required to make hundreds of subtle adjustments too how it reads that particular book, which would be worthless and inapplicable to any other. At the end of the day, it's a tool, used by a human, like a word processor, pagination software, or any sort of audio/video editor. Moreover, if I hadn't used the tool, I would have simply done the narration myself, as I did for the audiobook of my first novel, so the only person who might have potentially lost a job to it was me. 🙂
