The problem isn't the tool. Like all tools, it's just a tool. It can't do anything on it's own. The problem is that the tool is an economic super-weapon to destroy the entire professional art industry. Commissions? Fine art? Corporate art? Portraits? Concept art? Photo touch-up? Almost every kind of art where a single artist is hired to a produce an artistic work is severely threatened by this.

When the first water and steam powered mills were developed it destroyed the lives of untold thousands of people. The fruit of the industrial revolution was a massive drop in life expectancy and quality of life compounded with new forms of legal and economic impression.

The the automation of "Creative" jobs - copy writing, copy editing, fine art, singing, song writing, animation, dozens of other things currently under threat by "AI" tools, is going to produce a similar, if maybe less drastic, wave of immiseration. Countless disabled artists who rely on commissions and piece work are going to die in the streets because some chucklefuck bazinga nerd found a way to steal the sum total of human creative output and turn it in to a soulless, unthinking machine that produces facsimiles of creativity. Whole industries are going to disappear. It's possible, though unlikely, that entire techniques of artistic expression will be lost as the machine crushes everyone who knew how to apply those techniques.

The finest fabrics in the world were woven by hand before the invention of the steam loom. No cloth of comparable quality can be had in todays world, not for love or money, because the people who knew how to do it were destroyed by the industrial revolution and the techniques were lost.
