In a basic sense, this is true
Not really it's just wrong. The one approach that came from Western cultures is the scientific method which is both objective (to the maximum extent any human method has yet achieved) and universal which is why there is no such thing as Chinese, Canadian or Indian etc science there is just science because it is universal. As you alluded to the scientific method has often (including now to some degree) found itself at odds with western culture so I would argue that the scientific method is a product of western culture but not part of it.
Arguing that it is "culturally situated" is nonsense. While science has definitely impacted western culture it has also impacted every culture around the planet and today there are scientists in every continent from a myriad of different cultures. Your culture may impact which questions you want to answer with science but, if you are doing it correctly, it will not affect the knowledge you find and that's why it is both universal and acultural. Indeed, the universal nature of science means it is one of the few things that can bring people of different cultures to work together towards a common goal: to understand the objective reality that we all share.
This won't stop the copyright holders suing but that way it's just money passing hands between big corporations, Sony and Disney vs OpenAI or Microsoft or Google or whoever else.
How's that going to work exactly? How will Sony know whom to sue if they contact me and I tell them I made the video myself? If they do not believe me they will have to sue me to get a name and what happens if the court does not believe me too? Even if I did make the video with some AI company's product, I'd be the one who made money by uploading it not that AI company so why are they the ones who have to pay?
You can't cut the creator out of the legal process so easily: they are the only one who knows whether the video used any AI and they are also the one potentially making money from it. It's clear though that the problem is out-of-control greedy companies: the artists are caught between AI companies who want to trample over copyrights and studios who will dump them the instant a much cheaper, photo-realistic AI actor is practical. At the same time moves to strengthen copyrights against AI will almost certianly be abused by the same studios to come after creators.
I agree that laws should treat humans and AI algorithms differently but for that to work you have to be able to distinguish AI vs human work and so far we can't do that with anything like sufficient reliability..
This is clearly another case of too many mad scientists, and not enough hunchbacks.
