I don't understand why people assume that the purpose of any tool is to "replace humans". Automation doesn't replace humans and never has and never will. It simply does certain tasks that humans used to do, freeing people up to do different tasks. There is not a limited amount of work that can be done, there isn't a limited amount of _creative_ work that can be done. Even if AIs were good enough to do every creative task done by humans today (and they aren't and won't be any time soon), that doesn't mean that humans will have nothing of value to produce, or that humans will have been "replaced". There is always going to be work for humans to do, even in a universe where AI have super human capabilities at all tasks.

In particular, human beings strongly value the opinions and creative output of _human beings_ simply for the reason that they are human and similar to them. That will never change, no matter how intelligent that AIs get.
