Nope.

Not worried about it at all.

The images are - so far - sci-fi, fantasy, and incredibly cliche within the genre.

I have surveyed over 200 photographers (I do have access to that group) and not one assignment they have gotten in the past year could have been created by AI. AI doesn't make photographs, it makes digital collages on a molecular scale. It doesn't make design that is innovative, it makes deign that is predictable based on current models.

Creatives should keep a wary eye out, for sure, but relax. We are still in control of creativity based on intellectual abilities and non-predictive models of inspiration.
