AI is already writing news articles, composing pop music, and making graphics. All of it needs to be edited by humans, but the AI is able to reduce the amount of time the human needs to produce the work.
But AI only does things when asked to. It only builds up its database of background info when it is told to do so. It does not study on its own. It does not decide to write an article or compose a song. And that is where I think the technology will never be able to go. It will never have a will or an initiative. Humans are ultimately driven by a desire for food, companionship, and sex, and we have those desires regardless of if we are doing anything intelligent like speaking or planning, they are at a very base level. A computer program won't have any desires like that.
