I think AI generated content is nothing to be concerned about in general. Videogames, as an example, is not just an industry, it is a creative art form. If AIs start generating games that prove successful, well hey, great, that means we are enjoying them. But, real people are still going to continue making games of our own, because it is a way we express ourselves, and a way we connect with each other. When you play a game someone else made, you are going on an adventure through a part of that person's mind, as expressed through code and pixels. These organic aspects of it simply don't exist with AI, at least not any time soon. To that point, expression of personal imagination and creativity is an aspect of media that you will be able to get from only human creators. While algorithms may be a form of creativity, it remains a long way from anything that could be called imagination.
