There are some situations where AI might be acceptable. And that is training it on your own voice to help with the vocal creation process before doing actual recording, or helping to artificially hit notes you'd otherwise not be able to, or by using it similarly to autotune/vocoders. BUT With the proliferation of AI covers on YouTube, TikTok (and the internet in general), it's only a matter of time before someone trains a model to use voices from Linkin Park, which without express consent of each person's voice involved, I think is disrespectful and unethical. It also obscures fact from reality, giving someone the ability to pass off an AI creation as authentic. For example, someone could train an AI to use Chester or other Linkin Park member's voices to create a newly discovered LP "demo."
