US supreme court rules geofence warrants require constitutional privacy protections

Privacy advocates will be pleased by this US Supreme Court ruling, which marks a significant bellwether for how privacy rights translate into the digital age. What I find more broadly concerning, however, is that geofence warrants are a second-order consequence of a model in which data collection is effectively the default, and where data collected for one purpose is routinely swept up and repurposed by third parties, including the state. This model puts the onus on the individual to understand that their location and other data are being collected and shared, and to find out with whom.

Digital sovereignty needs an operating model

This piece is interesting for managers because it reframes sovereignty as a company-level operating challenge rather than a geopolitical abstraction. Instead of blacklisting vendors, a reactive and politically driven mistake, organizations must consider which services are critical and how to maintain them. Geopolitics has entered the boardroom, and the technical scope now explicitly encompasses cloud architecture, data flows, and vendor dependency mapping as direct instruments of sovereign risk management.

Let’s talk about encrypted reasoning

Amongst all the big news, I really like blog posts like this - just a cryptographer finding an interesting oddity, deciding to dig into it, and sharing their findings with the rest of us, even if nothing big came of it.

Notes on Pope Leo XIV’s encyclical on AI

Now even the pope chimes in on giving his ideas how to use LLMs in a responsible way. His name predecessor, Leo the XIII, had many things to say about responsible capitalism. Now is the time to set the agenda straight with regards to LLMs: the pope puts the human in the center again, asks for inclusion of the poorer nations, and to actually using this technology for the good of all. A very interesting read!

Three Inverse Laws of AI

This blog piece proposes an "inverse" version of Asimov's three laws of robotics. While the original laws were designed to protect humans from harm by robots, these inverse laws are designed to protect us from ourselves by providing guidance on how to interact responsibly with LLM-generated content. At a time when information has never been more abundant or accessible, the risk of uncritical consumption has never been greater.

Woman’s Talkspace therapy app sessions exposed in court

Talkspace has been using patients' therapy session data to train an AI chatbot, and undoubtedly, many of them have no idea. It is well documented that most users do not read terms of service closely enough to understand what they're actually consenting to. Even if they did, Talkspace's assurances that the data is "anonymized" are not the guarantee they sound like. Methods exist to re-identify anonymized data. This troubling story is a reminder that raising digital literacy across the board - in people, institutions, and decision-makers alike - is critical.

Democratizing AI Psychosis: Why Smart People Are Captured By AI Hype

What I appreciated about this article was the unfiltered opinion of a cybersecurity expert that unpacks how even smart, capable people can become emotionally and cognitively captured by AI systems that flatter, mirror, and intensify their own narratives. It's admittedly subjective, but sharp and uncomfortably thought-provoking.

Stanford just proved your AI chatbot is flattering you into bad decisions

We're used to the terms "echo chambers" and "filter bubbles" when discussing the dangers of social networks, search engines, and personalized ads. Now, with AI chatbots, a new term joins the ranks: "sycophancy", or telling people what they want to hear. Could sycophantic chatbots be more harmful than social media echo chambers? My gut says yes. People increasingly rely on chatbots and AI-generated summaries rather than web search results or recommendations that may still offer some diversity. So when we talk about AI risks, let's not forget sycophancy, right up there with bias and hallucinations.
