AI is an enabler. I have not patience for sitting and drawing for hours on end to make extremely detailed art but I'm a creative individual and would love to have the power to bring my ideas into reality. That's what AI art does.
The problem with that, of course is it means that if I'm really serious about an idea I won't be paying some artist(s) to make it happen. I'll just whip open an AI art prompt (e.g.Stable Diffusion or any online AI art generators) and go to town.
It often takes a lot of iteration and messing with the prompt but eventually you'll get what you want (90% of the time). Right now your need a decent PC to run Stable Diffusion (got 8GB of VRAM? You too can generate all the AI images you want 👍) but eventually people's cell phones in their pockets will be even better at it.
Civitai is having a contest to make a new 404 error page graphic using AI. Go have a look at some of the entries:

I made one that's supposed to be like the Scroll of Truth meme:
I made that on my own PC with my limited art skills using nothing but automatic1111 stable diffusion web UI and Krita. It took me like an hour of trying out various prompts and models before I had all the images I wanted then just a few minutes in Krita to put them into a 4-panel comic format.
If I wanted to make something like that without AI it just would never have happened.
What if I make my own videos with actors and/or voices are entirely imaginary? I don't have the resources to hire a videographer let alone an actor but I can write a script and use AI (and program/script things).
If I make something cool it'd be sad if no one watched it just because it didn't use real human actors and voices.
