People still paint, despite photoshop. People still play instruments, despite Digital Audio Workstations.

There is art in the craft, and more importantly enjoyment in the craft.

I wouldn't AI generate a song because all of the fun for me and my friends is in the playing and watching. You will find that's true very often for creative people and those who enjoy their work.

If all you are doing is blasting out corporate assets, or persuing money, I don't think anyone cares what you are using, generate away.
