"Fake posting activity" is a weak framing. It is real activity. The risk in allowing AI-generated content is that users will be able to sniff out low-quality content produced by AI that they don't find engaging, but if they don't like it they can always leave. If users love it then AI-generated content is not bad at all.
Why would anyone go to a forum for AI-generated content when they could just ask the AI themselves?
You also mean ”alternative truth” is the right framing to the otherwise weak framing of “lies”?
The "fake" aspect is the fact that it's presented as human activity. The risk is therefore that users identify low-quality content and then realize that the forum has no qualms about misusing/abusing existing accounts and misleading new ones.
Are you excited to generate an account and communicate with experts such as the ones in the article today?
Here’s the problem - it’s the same problem in many areas where AI is put to (ab)use:
I already have my own AI accounts. Several of them, really. Some of them paid. For work and for personal. If I want any kind of take from AI, which is in fact a very frequent occurrence, I can just prompt for one. For free even! And with my choice of model based on how important or complex the topic. There is zero value-add for me when some product decides to squirt an extra helping of AI somewhere it wasn’t needed. Summary of a long piece of text (while still giving access to the unabridged text)? Probably fine. An AI answer to a question someone else posted on a forum? Or injected above my web search results (looking right at you, Google)? No thanks!
