There. It isn’t even a “real” racism, it’s more of a flamebait, where the more outrageous and deranged a take is, the more likely it would captivate attention and possibly even provoke a reaction. Most likely they primarily wanted to earn some buck from viewer engagement, and didn’t care about the ethics of it. Maybe they also had the racist agendas, maybe not - but that’s just not the core of it.
And in the same spirit, the issue is not really racism or AI videos, but perversely incentivized attention economics. It just happened to manifest this way, but it could’ve been anything else - this is merely what happened to hit some journalist mental filters (suggesting that “racism” headlines attract attention those days, and so does “AI”).
And the only low-harm way - that I can think of - how to put this genie back in the bottle is to make sure everyone is well aware about how their attention is the new currency in the modern age, and spend it wisely, being aware about the addictive and self-reinforcing nature of some systems.
