I sat down with @JonHernandezIA in Madrid to discuss the growing risks and impacts of AI and the urgent need to improve our social, political, and technical safeguards. Thanks for an excellent conversation!
📁 Yoshua Bengio, Turing Award winner and AI pioneer, says AI agents are learning to pursue complex goals without human supervision. The danger is that once systems optimize for outcomes over instructions, they begin creating unethical subgoals on their own. As agency scales
I write about this in more detail in a blog post with a guest contribution from Isaac Rajagopal, a student at MIT on whose work ChatGPT built, who gives his assessment of the level of mathematical ability displayed by the model. gowers.wordpress.com/2026/05/08/a-r…
Anthropic CEO: "AI will write 100% of code within a year" developers spend 4 years in university learning to code Claude learned it from every book ever written if the hardest skill is already handled - the gap is no longer about what you know it's about how well you've configured the tool that knows everything most people haven't done that yet the article below is where you start
Today Federico Michelotto defends his thesis at University of Bologna ... congratulations Federico!
Prof. Donald Knuth opened his new paper with "Shock! Shock!" Claude Opus 4.6 had just solved an open problem he'd been working on for weeks — a graph decomposition conjecture from The Art of Computer Programming. He named the paper "Claude's Cycles." 31 explorations. ~1 hour. Knuth read the output, wrote the formal proof, and closed with: "It seems I'll have to revise my opinions about generative AI one of these days." The man who wrote the bible of computer science just said that. In a paper named after an AI. Paper: cs.stanford.edu/~knuth/papers/…
Don't forget to submit your abstract for the VeRoLog 2026 conference! The deadline is on Monday, the 23rd of February and this is this the website with all the relevant information lnkd.in/e2cvVWXF See you in Bath! #vehicleRouting
Here's my conversation all about AI in 2026, including technical breakthroughs, scaling laws, closed & open LLMs, programming & dev tooling (Claude Code, Cursor, etc), China vs US competition, training pipeline details (pre-, mid-, post-training), rapid evolution of LLMs, work culture, diffusion, robotics, tool use, compute (GPUs, TPUs, clusters), continual learning, long context, AGI timelines (including how stuff might go wrong), advice for beginners, education, a LOT of discussion about the future, and other topics. It's a great honor and pleasure for me to be able to do this kind of episode with two of my favorite people in the AI community: 1. Sebastian Raschka (@rasbt) 2. Nathan Lambert (@natolambert) They are both widely-respected machine learning researchers & engineers who also happen to be great communicators, educators, writers, and X posters. This was a whirlwind conversation: everything from the super-technical to the super-fun. It's here on X in full and is up everywhere else (see comment).

OCEAN is evolving 🌊, check it out! github.com/vidalt/OCEAN/ v2.0 offers a one-click Python library for optimal counterfactual explanations in tree ensembles (RFs, boosting...) based on MILP and CP models. Install with "pip install oceanpy". Unlike unstable heuristics that may treat similar users differently, OCEAN guarantees an explanation whenever one exists and delivers reliable results under a variety of plausibility or actionability conditions. The library is actively maintained by github.com/eminyous and members of the SCALE-AI Chair at @polymtl, with various additional features coming soon. #MachineLearning #XAI #Optimization #ORMS
