this is just the tip of the iceberg, and the paper contains much, much more: analyses of the top 100 domains, article subsets of elected officials and controversial topics, etc etc etc
please give it a read and let me know what you think!

we also found troubling instances of “auto-citogenesis,” or cases where:
- an X user asks the Grok chatbot something, then publishes the answer
- Grokipedia *cites that answer* without noting that it is a chatbot output
(the attached images are real examples of this)

- but a random sample of articles shows which topics have been heavily rewritten (history, politics, philosophy, biography) and which haven’t (STEM, sports, movies)
- grokipedia also targeted the wiki articles deemed highest quality for rewrites: the "featured article" and "good article" classes

- the primary distinction to make is whether grokipedia pages are cc-licensed or not—non-cc-licensed pages are presumably largely rewritten by grok
- many grokipedia pages (including those without cc licenses) are basically identical to their wiki counterparts, especially short ones

our paper tries to answer these questions
we find
- grokipedia pages are longer than wiki counterparts, and cite 2x more sources
- but citation standards are more lax than wiki: grok cites stormfront, infowars and many more
- non-CC licensed grokipedia pages increase blacklisted source cites 13x(!)

hi @alt.psingletary.com! you tagged the right person—I was working on this for a class project this semester
got it to a mvp stage about a week ago and hit pause to work on some other projects, but will keep working on it and would definitely would love to hear your feedback if you have any :)

There's a quickly-developing line of work on how insecure these agent systems can be, particularly when they have access to write and execute code.
The attacks on them are simple + devastating, up to and including reverse shells, data exfiltration, and more!

Modern Web browsers isolate untrusted content using the same-origin policy. AI agents today do not distinguish safe from unsafe content, nor data from (potentially malicious) instructions.

The narrative around AI safety shouldn’t be “Terminator” or “AI Chernobyl.” The right analogy is Netscape Navigator 1.0—the era when Web browsers first became a thing, and it was unclear how to protect users from potentially harmful Web content.
