This isn't really a problem with video generation or AI in general. Sure, there is an aspect of ragebait to it, but the reality is that racism is extremely widespread. If it were not, this kind of content would not be so popular. The people at the very top of US government right now are white supremacists. I'm sorry that is not an exaggeration. There is another term that encompasses more of their worldviews which is not politically correct but is accurate.
Stop trying to blame technology for longstanding social problems. That's a cop out.
Granted that racism is not new, the infinite production of automated content drowning out any genuine human opinion is a harbinger of the internet to come.
it also allows automated production of positive content. The main issue here is given a sea of good and a sea of bad content, where the typical person would go for a swim? Why calls for empathy fall flat while inciting rage and hatred is so successful?
It's entirely appropriate to blame a technology if the answer to the question, "Does this technology make a longstanding social problem worse or better?" is "It makes it worse."
There can be a follow-on discussion about what, if any, benefits are also provided by aforesaid technology
