Freethinkers are those who are willing to use their minds without prejudice and without fearing to understand things that clash with their own customs, privileges, or beliefs. This state of mind is not common, but it is essential for right thinking...—Lev Tolstoï

The average American worker using AI reports time savings of 6%, or 2.5 hours in a work week. Those are similar to the UK & Netherlands, and slightly more than other EU countries. There some early, non-causal, signs that this is translating into real gains in productivity growth

Garry Kasparov@Kasparov63·1d

Novel environments, no precedents or plagiarism possible. Humans 100%, AI <1%.

Guri Singh@heygurisingh

Humans: 100% Gemini 3.1 Pro: 0.37% GPT 5.4: 0.26% Opus 4.6: 0.25% Grok-4.20: 0.00% François Chollet just released ARC-AGI-3 -- the hardest AI test ever created. 135 novel game environments. No instructions. No rules. No goals given. Figure it out or fail. Untrained humans solved every single one. Every frontier AI model scored below 1%. Each environment was handcrafted by game designers. The AI gets dropped in and has to explore, discover what winning looks like, and adapt in real time. The scoring punishes brute force. If a human needs 10 actions and the AI needs 100, the AI doesn't get 10%. It gets 1%. You can't throw more compute at this. For context: ARC-AGI-1 is basically solved. Gemini scores 98% on it. ARC-AGI-2 went from 3% to 77% in under a year. Labs spent millions training on earlier versions. ARC-AGI-3 resets the entire scoreboard to near zero. The benchmark launched live at Y Combinator with a fireside between Chollet and Sam Altman. $2M in prizes on Kaggle. All winning solutions must be open-sourced. Scaling alone will not close this gap. We are nowhere near AGI. (Link in the comments)

Magnificent photo taken on the Ukrainian front. 🇺🇦 This soldier, still very young, appears exhausted. The cat, for its part, seems undoubtedly terrified. This is probably one of the most striking photos of this year 2025, regardless of how anyone views this war. And yet, in this embrace, it is difficult to say who is comforting the other. This image was not generated by artificial intelligence, nor was it a montage. It simply restores a little faith in humanity. Just a little. And that's already immense…

While social media is polarising, evidence suggests AI may nudge people towards the centre. This holds true of all studied models. Grok is more right-leaning than other models, but also has depolarising effects. By @jburnmurdoch.

Tim@TimurNegru·4d

The last time I was genuinely impressed by the amount of stylish people on streets was in San Sebastián, Spain. And I remember being surprised at the time. I can understand this happening in Milan, Paris, New York, London..but San Sebastián? So I did a bit of research. Turns out the Spanish royal court summered there every year from 1885. Naturally, the aristocracy followed. So dressing well in public became the norm. Btw, Cristóbal Balenciaga (one of the greatest couturiers who ever lived) opened his first boutique there in 1919. His early clients were Basque nobility and Spanish royalty. In terms of fashion style, it's not flashy or Mediterranean. The Basque aesthetic leans toward quality, restraint, and fit. Which is closer to French sensibility (the French border is only 20km away) than Andalusian.

We have just endured the 11 hottest years on record. When history repeats itself 11 times, it's no longer a coincidence. It's a call to act. Climate chaos is accelerating & delay is deadly. The way ahead must be grounded in science, common sense & the courage to act. #ActNow

Euromaidan Press@EuromaidanPress·6d

For every dollar Denmark spends on Ukraine, France sends 7 cents, Italy 7 cents, the US zero. Denmark has given 3.25% of GDP—the highest in the world. On election day, Ukraine barely comes up. Not because Danes don't care—70% agree on keeping the support going. A reporter walked Aarhus asking voters. Out of 40–50 people, one disagreed. His wife interrupted him. If all NATO countries had matched Denmark, Ukraine would have received $2 trillion—not $350 billion. euromaidanpress.com/2026/03/24/den…

5 minutes before Trump’s announcement: * $1.5B notional worth of S&P500 (ES) futures are bought in a single clip. * $192M notional of oil futures (CL) sold. More than 4x-6x any other trade size during the market close. Insiders profited from his lies in broad daylight!
