The bots are taking over
Digest
The podcast explores two related topics: a purported indicator of AI-generated text and an ethical breach in AI research. The first segment examines the online theory that excessive use of em dashes signals AI authorship. The hosts analyze this claim, referencing data showing a recent increase in em dash usage and debating its validity as a reliable indicator. The second segment details a controversial experiment conducted by researchers at the University of Zurich on Reddit's Change My View (CMV) subreddit. These researchers used AI-generated comments without disclosing this fact, leading to significant backlash and raising serious ethical concerns about manipulation, deception, and the violation of community trust. The researchers subsequently apologized, ended the experiment, and faced potential legal action from Reddit. The discussion highlights the ethical implications of AI usage in online communities and the need for transparency and informed consent in AI research.

Show Notes
The bots are here to stay, and they're everywhere. The trouble is, learning how to spot them.
On this week's episode of Endless Thread, Ben and Amory discuss two stories from Reddit about undercover bots. First — is there such a thing as an easy tell for identifying bots? Second, what happens when internet users accept bots as fellow humans, only to discover the truth later?
