That's your opinion. I disagree with it. Keep the banner as it is. Someone surely took the time to make that image. As it's pretty good even more for the time it was created. You are just dishing that person's work. I respect that person work, so the banner should stay.

It would be fine if it was possible to ask the person who made the banner how did they made it and how long it took.

Your complain seems to be mostly based on AI being able to do things faster. At that point why stop there.. don't hire digital artist. They took jobs away from traditional artists. Pretty sure the only good thing we could do I commission the banner to a full crew of sculptors to do the 3d mesh on granite and then a full tome oil painter for a year to capture the image into canvas. That would make sure that not technological advances would steal anyone's job.

Edit: It's fucking ironic that anti-AI people use downvote/ upvote bots. But I catched it. Fucking ironic.
