#Wikipedia #WikimediaCH #WikipediaDay

Closing the lightning session with a video at #WikipediaDay NYC featuring @Pharos and a bunch of CUNY students and professors about making Wikipedia editing a part of CUNY and getting info about CUNY into Wikipedia

(sponsored by Craig Newmark)

Next lighting talk at #WikipediaDay NYC is @antisomniac discussing updates regarding Agentic AI on Wikipedia

"While every company is stuffing AI into everything, we've decided to remain human to a fault"

And that the recent incident with "TomWikiAssist" was a best-case scenario because it disclosed itself.

Takeaway: Every crowdsourcing project needs a plan for agentic AI

Jack McCarthy is putting the "lightning" lightning talk at #WikipediaDay NYC with a super-fast talk about how math formalization will help Wikipedia (so many great slides I wasn't able to take pics of)

Quick he asks, this is a proof from Wikipedia, which is right and which is wrong?

In short, math articles should be verified/connected to proofs, using Lean which is open source

Next #WikipediaDay NYC lighting talk: Prerit Pathak about "Cyber for Social Impact" discussing cyberattacks against non-profits and how not having cell service in subway tunnels can be a good thing.
