If companies should be beholden to some ethical standard for the generations, they should probably close up shop, because they're fundamentally nondeterministic. Language models, for example, only produce plausibilities. You'll never be able to take even something in its context and guarantee it'll spit out something that's "100% correct" in response to a query or question on that information.
>And on top of that, companies also have to account for the potential of intentional trolling campaigns.
Yeah, they surely should "account" for them. I'm sure the individual responsible for the generation can be prosecuted under already existing laws. It's not really about safety at that point, and realistically about the corporation avoiding AGs raiding their office every week because someone incited a riot.
Ultimately, the cat's out of the bag in this case, and anyone who has amassed enough data and is motivated enough doesn't have to go to some AI startup to do any of this.
But perhaps the issue is not generative AI at that point, but humanity. Generated images light up like a Christmas tree with Error Level Analysis, so it's not hard at all to "detect" them.
