It seems to me that the ethics of using learning software are nothing more than an intellectual exercise. It is already cheaper to use software to generate reports, presentations, and artwork than to do it "manually". Most of our planet runs on greed capitalism, which means that the solution that makes the most money will eventually be accepted. John Henry does not win -- the steam drill does. (And we're seeing very primitive examples of "AI" so far.)
The introduction of the power loom in the early industrial revolution turned weaving from a cottage industry employing most of the rural communities in England into a sweatshop industry employing orders of magnitude less. It ruined quite a few lives and arguably made many more worse. People hated it even at the time, but their anger made little difference in the end.
My advice to artists is to roll with the punch and start using the new software. If you don't, your competitor will.
And, in the end, learning software is just a force multiplier. It does nothing on its own. A human still has to decide if the result is useful or not. (This is why making decisions based on AI is so dangerous -- by the time you know if the result was useful, it's probably too late.) So, there will still be jobs for artists, just not as many.
Now, on a side note. This is the outcome programmers have been working at for most of a century. This is our nirvana -- the machine does the work, with minimal intervention. Programmers are lazy by nature; that's why we're willing to spend days coding a utility that will save a few hours of effort. Be careful what you wish for.
