The human imagination also involves the phenomenal experience. You do not just record the data coming at you and regurgitate it, you experience it and then your experience further changes the data itself. We call this “subjectivity” and it’s where creativity comes from.
I am not saying that machine creativity is impossible. What I’m saying is these LLMs are not creative because they don’t even know what they’re doing and they don’t even know “they” are doing it. There’s no “there” there. No more creative than rolling dice.
