Know what else plays fast and loose with copyrighted characters? The hundreds of artists who every day take money from people to draw pictures of them without a license or consent, which is illegal. Why is that "okay" when using AI to do the same thing is not?
I keep seeing this stupid question from so many people it's really becoming annoying.
I won't even respond to the obvious whataboutism because we can definitely tackle two things at once and we should prioritize more important of the two which in this case is definitely "AI".
You know what's the difference between a human doing drawing and "AI" doing drawing?
The SCALE at which "AI" can do this -- no human artist can:
1. Memorize exactly the likeness of every character known to man
2. Learn hundreds of different drawing styles
3. Be able to mix and match those styles with consistent results
4. Modify specific character features on a whim
5. Output one image per second (or more on hardware faster than RTX 4090)
6. Never get tired at all, much less of producing endless variations of the same thing
7. Have theoretically unlimited capacity for learning new stuff
8. Learn new stuff at the rate "AI" can, even if it had the same capacity
So, you are comparing hundreds of human artists where each takes anywhere from couple of hours to couple of days per commission to produce ONE image for someone's personal use to make a living, and an "AI" produced by a megacorp by scraping everything and the kitchen sink without permission which is enabling literally hundreds of millions of random people who aren't even artists to produce a venerable flood of drawings either for free (by mining your personal data) or for a small fee, both of which enrich said megacorp.
And you still don't see the difference? Or you just don't want to see it?
It's a rhetorical question -- no need to answer since it's obvious that you haven't given the subject much thought when you are comparing apples and oranges like that.
