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?
First and foremost, where all this AI gets its results from queries, it's coming from the human output too. They do not have a mind of their own to produce results; I don't trust AI because some of its results are outdated and lack imagination and just combine what's on their database.
AI can assist human creativity and imagination, but it's the human judgment that finalizes the works.
There are many industries that are now employing these AI, but we still need humans to monitor these AI on their results.
