It's the recognition of perceived merit based on effort. If you believe the human artist did nothing more than you could have done yourself with your current skills, it's natural to devalue the work. Sometimes that effort is intellectual, sometimes it's just brute force, and most often it's reflective of years of training and honing of skills that might be commonplace. At some point you might value the artwork, but not the human artist because you don't think much effort was expended to achieve that work.

In this case the article says:

  "Allen created Théâtre D’opéra Spatial by entering various words and phrases 
  into Midjourney, which then produced more than 900 renderings for him to 
  choose from. He selected his three favorites, then continued adjusting them 
  in Photoshop until he was satisfied. He boosted their resolution using a tool
  called Gigapixel and printed the works on canvas."

The artist claims 80 hours. Is that enough effort? It's certainly not turnkey. That's the question.

Yes. It took time, not effort.
