If AI has no creativity then it shouldn't be able to compete in the slightest with actual humans, having creativity is such a fundamental aspect of creation that you would think that something that doesn't have it shouldn't even be comparable, yet many are worried.
Anyone who cares about public health would be worried that so many people eat slop from McDonald's. But if McDonald's food is bad and unhealthy, it shouldn't be able to compete in the slightest with real food.
Food from McDonald's is as real as healthy food, it's food, there's nothing fundamentally different, just lower quality, if that's the point, then you're saying there's also nothing fundamentally different from stuff created by humans or by an AI, just lower quality.
We'd be a healthier society if the early days of ultra processed food had been met with skepticism instead of prostration to corporations changing the nature of food for profit.
A human can be less or more creative, there is always some creativity, but for a machine it is controversial to say if there is any creativity at all. Going from not very creative to very creative seems to be a much easier task than creating a machine with some creativity to begin with.
