> intent matters
Ironically, machines autogenerating Seinfeld-like scripts literally cannot have intent.
We can go a step back to the intent of the creators of the system. I assume the creators did not intend to auto-generate distasteful and/or bigoted jokes. But it's Seinfeld-like. And it seems if it's supposed to generate bad jokes eventually it'll make some mean jokes.
It's something of an interesting thought experiment about intent vs. effect with publication of speech. All effect, no intent.
Prima facie, I can see the logic in treating the operator of the AI legally/socially responsible in the same way as if they had published the material themselves. If you unleash a bot that e.g. goes around writing defamatory book reviews, you should be liable for defamation. But I am not sure.
