In case you didn’t know, you can’t train an AI on content generated by another AI because it causes distortion that reduces the quality of the output. It is also very difficult to filter out AI text from human text in a database. This phenomenon is known as AI collapse.
So if you were to start using AI to generate comments and posts on Reddit, their database would be less useful for training AI and therefore the company wouldn’t be able to sell it for that purpose.
This is incorrect in the general case. You can run into problems if you do it incorrectly or in a naive manner. But this is stuff that the professionals have figured out months or years ago already. A lot of the better AIs these days are trained on “synthetic data”, which is data that’s been generated by other AIs.
I’ve seen a lot of people fall for wishful thinking on this subject. They don’t like AI for whatever reason, they hear some news article that says something that sounds like “AI won’t work because of problem X”, and so they grab hold of that. “Model collapse” is one of those things, it’s not really a problem that serious researchers consider insurmountable.
If you don’t want Reddit to use your posts to train AI then don’t post on Reddit. If you already did post on Reddit, it’s too late, you already gave them your content. Bear this in mind next time you join a social media site, I guess.
