Mayor Zohran Kwame Mamdani @mayor.nyc.gov · 19h
53 years ago, hip-hop was born at a back-to-school party in the Bronx. Now, the Bronx School of Hip Hop is preparing a new generation of artists to shape what comes next. I sat down with Nas to talk about the past, present, and future of hip-hop in NYC — from the turntables to our classrooms.

New ways to fight online #disinformation. How public institutions can get a handle on #AI. How civil society pushes back against election interference. This week, we’re speaking at and taking part in a range of events. Different topics, same goal: building a safer online environment for everyone. ⤵️

This isn't just a policy gap; it's a strategic gap that affects how credible Europe's regulatory framework (DSA, AI act...) can be long-term, and really effective. #DigitalSovereignty #FIMI #MediaEcosystem #EUtech #Disinformation

Hervé Letoqueux @herve.checkfirst.network · 28/09/2026
The argument is straightforward: digital sovereignty requires funding the oversight infrastructure, not just the technology itself. A proposed solution is integration into the next EU seven-year budget cycle.

Hervé Letoqueux @herve.checkfirst.network · 28/09/2026
For the media ecosystem and anti-FIMI work, this dependency creates structural vulns. Private companies like @checkfirst.network, independent researchers, fact-checkers, and civil society groups cannot guarantee continuity if foreign funding shifts; a risk during actual geopolitical tensions.

- Only 12% of the Democracy Stack's annual budget comes from EU institutional funds - nearly 60% relies on US government or philanthropic sources - total Democracy Stack operating budget: €144M/year

This article from @techpolicypress.bsky.social highlights a troubling imbalance in the EU's digital strategy: while Brussels commits €400+ billion to AI and semiconductor infrastructure, the independent bodies responsible for democratic oversight remain heavily dependent on external funding.

Pt 3: I made this post about Google AI summaries misinforming us. Now Futurism reports that these summaries are only accurate 91% of the time. At the scale of summaries they produce, that means Google, itself, is producing 450 billion pieces of misinformation yearly! futurism.com/artificial-i...
Analysis Finds That Google’s AI Overviews Are Providing Misinformation at a Scale Possibly Unprecedented in the History of Human Civilization

Google’s AI Overviews are peddling misinformation on a scale that may be virtually unprecedented in human history.

A recent analysis conducted by the AI startup Oumi at the behest of The New York Times found that the AI-generated summaries, which appear above Google search results, are accurate around 91 percent of the time. 

five trillion. That’s roughly the number of search queries that Google processes every year, translating to tens of millions of wrong answers that the AI Overviews are providing every hour — and hundreds of thousands every minute, the analysis calculated.

In other words, Google has created a misinformation crisis.

The parallel is striking: what happened to malware analysis (public disappearance, paywalls, geopolitical bias) already threatens FIMI analysis. IMS adapt, their operations grow opaque, and our collective ability to understand them publicly diminishes. #FIMI #disinfo

Like malware, IMS evolve: automation, ML, composite infrastructures. The most detailed FIMI analyses will increasingly sit behind paywalls or confidentiality classifications. Public transparency will shrink while complexity grows.
