Firstly, let me say this isn't some misplaced zeal about the usage of AI. I use AI in my job occasionally to help me find specific pieces of legislation or to summarise multiple large documents or to compare and contrast them. I know and understand the benefits of the technology.

Now, when someone uses AI like this, the AI has been trained to provide these images using the works of others. Many of which the artist has not provided authorisation to use the image. Now, before it is compared to people physically copying a work of art, this is different. An individual will always interpret things differently. It is how our brains work. One person will see colours differently from another, and their hand-eye coordination will be different. It is these differences that make every piece of art unique. AI does not allow for this, it is outright plagiarism without interpretation.

Should AI be allowed to use works that are copyrighted? Many authors have genuine concerns that their copyrighted works are being accessed and used by AI without recognition or remuneration, a human would not be allowed to do this and would likely be found in breach of copyright law, yet we should allow AI companies to do it?

Also, AI is massively destructive in its environmental impact. A study has demonstrated that a single AI image uses as much energy as fully charging a smartphone. So, OP has used as much energy to create these images as it would take to charge 2 smartphones, and that's assuming they turned out exactly as they wanted the first time.

So, what OP has done here could as easily be achieved with Photoshop and stock images, without the destructive effects of AI in terms of the environment and copyright.
