I can instruct an AI to draw Mickey Mouse and infringe copyright and I can instruct a child to draw Mickey Mouse and infringe copyright.
And when you try and sell that work without attribution or compensation then there is a problem.
Exactly. If I produce a work, and then you produce an identical-enough work, you're infringing my copyright. I don't care how you did it, it makes absolutely no difference to me.
The problem is there's no way a user will know whose copyright they are infringing when they ask AI to "paint a landscape."
Maybe the AI needs to be able to print out a list of sources to provide attribution. That would be interesting.
Artists get inspired by others all the time, and if the results are far enough from each other, then nobody has a problem with that. In fact, pre copyright, the similarities used to be even larger. Art lives from the concept of taking ideas, and improving on them.
> they ask AI to "paint a landscape."
that's the responsibility of the user said AI to check.
