The capabilities of current generation AI—LLMs + audio/image/video generative models—are far enough already that wide-scale distribution is extremely dangerous.
Social media allowed for broadcasting from 1:many and 1:1 with troll armies, but LLMs are on a whole other planet of misinformation. A scalable natural language interface can target people at the one-to-one conversation level and generate misinformation ad hoc across text, voice, images, and video.
The trouble with this approach is that harm will rack up way faster than liability can catch up, with irreversible and sometimes immeasurable long term effects. We have yet to contend with the downstream effects of social media and engagement hacking, for example, and suing Facebook out of existence wouldn't put a dent in it.
Current generation AI has enough capabilities to swing the 2024 US presidential election. It can be used today for ransom pleas trained on your childrens' instagram posts. It doesn't seem farfetched that AI could start a war. Not because it's SkyNet, but because we've put together the tools to influence already-powerful-enough human forces into civilization-level catastrophe.
