I think AI excels in how to make things faster and efficient, the creativity in itself will just depends on the data supplied meaning the creativity will probably just the same as human peak creativity.
like basically you can ask AI to recreate mona lisa painting by giving simple prompt, but can it create a painting that's better in term of creativity compared to mona lisa? I doubt it could. I even doubt it even understand what creativity really is by human's value, the AI hasn't reached that level yet.
But if you use AI to make many aspects of life efficient, sure it has really huge unexplored potential, for example, human requires days to years to create an animation that probably only have duration of 30 seconds, with generative AI model trained to make animation, it could do it within few seconds as long as the computing power is huge enough.
I will however like to hear your thoughts (not ethically but practically) on "if AI can be trained to be creative and if it's creativity can surpass human spontaneity?" and are project like these worth investing in?
Of course it is worth investing, undeniably AI is the future, its always invest early and become the winner or be doubtful and miss the best opportunity to invest, basically this kind of thing.
