🧠 Yann LeCun leaves Meta to build a startup around ‘world models’
LeCun’s decision highlights the tension between exploratory AI research and the corporate race for profit-driven innovation. His emphasis on world models could revive interest in more structured and reasoning-oriented AI architectures beyond current language model trends.
Yann LeCun, Meta’s Chief AI Scientist, is leaving the company to found a new AI venture focused on developing ‘world models’—an emerging framework for machine reasoning that leverages spatial and visual understanding. His exit follows Meta’s strategic pivot toward large language models and commercial AI initiatives under its new Superintelligence division. The move reflects deeper philosophical divides within Meta’s AI leadership and signals renewed interest in alternative approaches to human-like cognition.

🖼️ The Agentic Pelican Experiment: When AI learns to draw itself better
A witty exploration of self-improving AI models that use their own output as feedback—highlighting both the promise and the limits of ‘agentic’ creativity in current generative systems.
This experiment tasked multimodal AI systems—including Claude, GPT-5, and Gemini—with iteratively improving an SVG illustration of a pelican riding a bicycle. By comparing how each model refines its own output through visual feedback loops, the study reveals how differently AIs assess and enhance their creations—some achieving realistic mechanical refinements, others introducing unnecessary complexity.

📏 Why subscripts and sizes in C++ should be signed
A fascinating look into the evolution of C++ design philosophy—showing how even core conventions are being revisited to prioritize safety, clarity, and logical consistency.
In this C++ standards paper, Bjarne Stroustrup argues for adopting signed integers for subscripts and sizes in the standard library. He examines the historical reasons behind unsigned types, their pitfalls—such as confusing conversions and hidden bugs—and justifies the use of signed indices in `std::span`. Stroustrup advocates a gradual shift toward mathematically consistent and safer signed semantics across C++.
