Des médecins voient leurs performances baisser après avoir utilisé l’IA: le «deskilling» gagne du terrain

Le Temps — 21/06/2026

Linus' take

"

Voilà qui est intéressant, mais guère surprenant : lorsque l'on s'appuie sur les intelligences artificielles, on perd peu à peu l'habitude de ce que l'on savait faire par soi-même. C'est probablement analogue au fait de ne plus être capable de marcher de longues distances quand on prend constamment la voiture ou le train. J'aurais bien aimé savoir si les utilisateurs et utilisatrices de l'IA en retirent par ailleurs d'autres bénéfices — ou si leur esprit critique s'émousse lui aussi, nous entraînant vers un monde où nous ne serions plus capables de distinguer ce qui nous aide de ce qui nous nuit.

Chile turned to China for an undersea cable. The U.S. said no

Rest of World — 18/06/2026

Olivier's take

"

This article serves as a reminder that the digital world relies entirely on physical infrastructure and its geopolitical importance. The proposed cable from Chile to Hong Kong became a test of how far the U.S. would go to curb China's telecommunications ambitions, with Washington blocking the project and encouraging Chile to choose Google's alternative. As Europe's sovereignty strategy unfolds, the warning is clear: controlling infrastructure is a form of raw geopolitical power. Similar diplomatic, economic or regulatory retaliation, such as tariffs, licensing, or access conditions, could easily target Europe next.

AI Use by the US Government

Schneier on Security — 17/06/2026

Carine's take

"

While I generally agree with this nuanced discussion about how use of 'AI' in a plethora of government processes is neither new nor necessarily bad, I think an important point that it only indirectly addresses is that we should avoid using these systems as a panacea for overrun and underfunded public services.

Digital sovereignty needs an operating model

The Register — 17/06/2026

Olivier's take

"

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.

World’s first wind-powered underwater datacentre starts operating in China

The Guardian — 09/06/2026

Katherine's take

"

It is an oversimplification, but I find it useful to contrast two different approaches to AI sovereignty: China's public sector-led model versus the private sector-led approach exemplified by the US. What I find most striking is China's ability to advance a strategy that serves multiple goals simultaneously, from climate action to AI infrastructure, with impressive coordination and unified vision. That level of coherence makes me reflect on how steep the path to AI sovereignty is for a region like the EU, composed of 27 member states, each with their own strategic priorities.

10 November 2026: C4DT Conference on AI Sovereignty: Charting Switzerland’s Path Amid US and Chinese AI Dominance

 

Where? Starling Hotel, 1025 Saint-Sulpice

 

Time? 9:30 – 18:30

 

Why participate?

 

As the global AI landscape consolidates around US and Chinese dominance, every nation outside this duopoly faces an urgent question: how can countries retain meaningful control over a technology increasingly expected to shape their economic competitiveness, national security, and societal resilience? From the viability of sovereign cloud architectures and open-weight foundation models to the governance mechanisms needed to ensure AI systems reflect Swiss values and legal frameworks, this conference brings together industry leaders, researchers, legal experts, policymakers, and civil society actors to assess the concrete levers of AI sovereignty and work toward actionable recommendations for a Swiss sovereign AI strategy.

This event is organized by the Center for Digital Trust (C4DT), EPFL.
