(a sharp distinction from Sniffles the teacup poodle. I don’t care if you think you’re happy, this would not please the prowling wolves of the stone age.)
This is indeed very much the obvious failure mode! Discovering that an alien species has bred a group of humans into what a pug is to a wolf would be absolutely horrific.
Moreover the path between utopia and “lovecraftian horror” seems pretty fragile? I don’t know exactly what property cats had that made the shoggoth take the good one (mostly, maybe except for those flat-faced Persian and hairless Sphynxes) for them, and it’s plausible it was just a lucky combination of minor stuff (harder to selectively breed, different social niche, different types of people liking cats) that won’t be stable/generalize in extremis.
I predict we are shortly going to see platforms using generative AI + A/B testing to make “hyperslop”.
Imagine a music service, or a TikTok-like platform with AI-generated shortform videos. The generator gets hooked up to an optimiser which tweaks its input parameters. These could be legible, such as “colour saturation”, “cuteness”, or “content variability”, or entirely opaque weights somewhere. If a tweak is statistically established to increase engagement, it is applied and another A/B test begins.
You could even have specific optimisers which gets run on various subgroups, like “female American teens 16-18” gets their own sub-optimiser, as well as every subculture and every little attractor basin you can identify. This could go all the way down to tweaks for each individual user if content is cheap enough to be personalised.
All the prerequisites for this already exist. We’ve already gotten a taste of it from YouTube thumbnails, which have been A/B gradient-descended for years on the minds of a billion of mostly children to plaster those inhuman staring open-mouthed faces everywhere. It’s just a matter of time before bulk AI generation gets cheap enough to speed it up thousands of times and apply it to the content itself.
