AI doesn't add more danger to the situation, you just need to moderate as usual. If you are using some computer program to add more content to your web site, you will just have more content to moderate. News aggregators do have this problem for example, as sometimes automated crawlers post sensitive content and that needs to be marked & deleted before being published.
Saying, "oh but our algorithm can cause depression, so we moderate the access to it" doesn't make sense, as any content can cause it and needs to be moderated.
That's why content moderation is one of the hardest problems of this age.
You use computers to do it? Computers develop biases. Humans? Same! It's very hard to scale and is a problem only remotely related to AI-generated content because AI generating content increases the input to your moderation system.
Now I hope it is clear what I'm trying to say :)
Objectively yes. Information on correctly peeling a pineapple is ok? Processing chicken to cook it? What about a dog? A rat? Fish? Insects? Is killing millions of bacteria with a single drop of chemical okay? Ways to commit suicide? What if this video is for prevention?
When it comes to moderation, we can't even set a consistent rule set to "deal with it all (c)". We just wing it, and hope it matches the expectations of our majority of our users... and the government(s)! Yeah governments have rules, but they tend to change towards the expectations, and a lot of rules for interpretation. It's a very hard task.
> For that matter, can knowledge exist without bias?
Umm... I don't know what that would mean. Isn't science there to reduce the amount of bias in knowledge? So, maybe, no? We can hope to reduce it, but we cannot get rid of it? At this point I don't really know what I'm talking about to be honest :)
