AI is already in commercials, TV, and movies. Companies for the most part just don't tell you because the reaction of the general public is "eww, AI".
It's already here in a big way. You just won't be told about it until the public lightens up on the "AI hate".
I think the vagueness of statements like this is why a lot of people (myself included) are just so very skeptical. Surely some company wants to brag about their use. I don’t doubt it’s found its way into certain spaces, but by and large a lot of the “big” claims have been demonstrated to be borderline fraudulent. That Brad Pitt/Tom Cruise AI fight is fake. It is misleading. Taking existing green screen choreography and using AI to impose Brad Pitt and Tom Cruise’s faces is not what it is being sold as. Darren Aronofsky’s AI works are not good either. They can’t seem to hold a shot for more than a few seconds, why is that?
If the argument is that AI is being used in the background or for some VFX, sure, I’ll buy that. It’s just another tool, then. If it is being used to generate entire scenes, there’s no evidence of this, unless something like that atrocious holiday Coca-Cola commercial is a herald of our future.
As written, your claim is just handwavy. I get you might not be able to cite anything concrete due to NDAs or whatnot but, you also have to understand why a lot of people find this kinda unpersuasive.
