I don’t understand the odd jump to teenagers on Deviantart. You sound like you have an axe to grind.
I don’t know why you attribute to the deviantart community the status of teenagers, and I also don’t know why you think that there aren’t talented and seasoned artists all over the world making beautiful expressions in a diverse spectrum of media.
Are you bitter about something? I don’t like AI art whatsoever and I don’t think it deserves to be called art. It’s sewage. I also think that individuals who like that crap distinguish themselves as unsophisticated and dumb. I think most people with taste feel this way. So what’s got you worried?
OK I hear ya. I think like anything, a low-quality, low-effort, low-cost product will appeal to a certain demographic, and there will be no shortage of bottom-feeders who will peddle it for a buck.
