In a post-scarcity solarpunk future, I could imagine some reasonable uses, but that’s not the world we’re living in yet.
AI art has already poisoned the creative environment. I commissioned an artist for my latest solarpunk novel, and they used AI without telling me. I had to scrap that illustration. Then the next person I tried to hire claimed they could do the work without AI but in fact they could not.
All that is to say, fuck generative AI and fuck capitalism!
It may have suffered, but it's distinctive.
The webcomic space is flooded with generic "good art". If you want to stand out and build or maintain your brand - you need a unique look. Artists want their audience to be able to look at a character and instantly know they drew it.
(The best example of this is perhaps the worst human being in webcomics today. You can recognize his style in the first three lines of a face.)
I think PA was in kind of a bad place, because they were popular so early in the webcomic boom and so many people copied their style that their original art became generic. What's going to attract a new teenage reader to PA if it looks just like every other crappy "two guys on a couch playing video games" webcomic they've seen?
So PA had to change their style. And say what you will about it, there's no doubt who drew (or had an AI tool draw) those characters.
