AI will never create something new.
Although, it might appear to be by accident.

There are tons of art ideas i have that i count the time and resources to build, and never get to it.
With the help of AI as a tool, i might do them.

What most people do not know is the bleeding edge of reality creation.
Most people are quite a few steps away from it.

There are people out there making really new music. So new that the common person finds it annoying. Not pleasant to listen to. An AI can not do this.
Then, more musicians start picking up on the ideas of the new music and start working it into their songs.
And lastly, it is on the top 20 radio station.
At that point, the AI can make a pretty decent copy.... modified copy

I deal with many people who are on the bleeding edge or reality creation.
For these people, AI is not even a good tool.

However, i also know many people who design web pages, and except for getting color themes right, and having a new set of photos, everything is just repetition.
