I'm pretty sure the CJEU in Russmedia just casually dismantled 80% of the DSA with one ill-considered judgment. As I read it, it substitutes in GDPR rules -- not notice and takedown rules -- for any platform where a user is likely to post content about people. 1/

AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

Is social media dying? How much has Twitter changed as it became X? Which party now dominates the conversation?
Using nationally representative ANES data from 2020 & 2024, I map how the U.S. social media landscape has transformed.
Here are the key take-aways 🧵

In the literature, there are two competing explanations for "echo chambers":
1️⃣ Algorithms curate what we see (“filter bubbles”)
2️⃣ People choose like-minded peers (“selective exposure”)
Our new study suggests something surprising:
both explanations might be wrong. 🧵

Ever since I started thinking seriously about AI value alignment in 2016-7, I've been frustrated by the inadequacy of utility+RL theory to account for the richness of human values.
Glad to be part of a larger team now moving beyond those thin theories towards thicker ones.

Often our tech policy interventions operate from linear, top-down assumptions that don't account for the complexity they seek to govern.

This level of agreement is particularly noteworthy because, at the beginning of the process, the substrate of trust that makes dialogue (and Track II diplomacy) possible among peacebuilders in the region had (understandably) grown fragile.

The process resulted in a joint letter to the international community with a set of five demands, each of which has at least 90% of support from participants on each 'side'.

In April – July 2024, in collaboration with the Alliance for Middle-East Peace (ALLMEP), we conducted a series of online collective dialogues with civil society peacebuilders in Israel and Palestine, and used LLMs and bridging-based ranking to surface ideas that had broad support across groups.

You might have heard of the "Habermas Machine", an AI-human pipeline that is really good at finding common ground between ideologically diverse groups, at least in lab settings.
But can this kind of approach help in real world conflicts?
