I remain an unrepentant Butlerian Jihadist on the use of AI in art, and highly, highly suspicious on AI in general in any case. I am very concerned about a slippery slope to any number of dystopian scenarios, and "Open the pod bay doors, please HAL". I think people are rushing headlong into this, without considering the many potentially horrifying implications. History has proved mankind is reckless and foolish with technology, often perverting it into instruments of oppression or weapons. AI has the potential to be exactly the same, and worse.
Leaving aside that bigger question, if a vocal performance is adjusted by a machine it has been adjusted by a machine, no matter how much hair-splitting you throw at the argument. I fundamentally believe this is not the same a sound engineer making manual tweaks.
We should allow room for AI "experiments" with film? As far as I'm concerned, hell, no. Certainly not if you expect me to consider it as a human endeavour, potentially worthy of awards. Will I get my way? Almost certainly not. But that doesn't mean I have to like it, approve of it, or respect it. I don't. I see it as a potentially hugely destructive plague on artistic livelihoods and our collective humanity.
