What makes mass produced bland is not that it lacks human creativity it's it's the exact same model and color iPhone * 10,000,000 because it's cheaper. You can just as easily plug in something else with creativity and not pay the lowest possible price as you can plug in human creativity and not pay the lowest possible price. Current ML models aren't great at coming up with their own variations on things and if you want to call that "human creativity" then sure but I'm firmly in the camp that type of creativity isn't something forever bound to being human for the rest of time.
