you also claim that it’s possible to wash off the authorship and copyright of a work by passing it through an algorithm
I do not need to claim this. That's how copyright works. Look up, what a collage is as an example how weird copyright is. And that's why it is pointless to try argue with copyright against ai.
There's a difference between a function that is reversible and one that is not. Zip is reversible. A learning matrix is not.
I am not arguing against or for ai. I am arguing against your argument against ai. Preference for human work is a far more stable and longer lasting argument. And it will also work against ai that would be trained entirely by commissioned work.
