I think AI "art" can be as useful as the text generators, i.e. only within certain limits of dull and stupid stuff that needs to exist but has little to no value.
For example, you need to generate a landing page for your boring company: text, images, videos and the overall design (as well as code!) can be and should be generated because... who cares about your boring company's landing page, right?
Then you don't understand the purpose of a landing page. If the boring company hires somebody to make the landing page who actually understands their job, the landing page will have great importance.
One could ask why the boring company landing page exists in the first place though. If it's not providing value to humans to warrant actual attention being paid to it...
