Jordi Visser uses a diverse AI tool stack daily, including Perplexity, Gemini, ChatGPT, GROQ, and Claude, to conduct rapid research and generate content, highlighting the significant productivity gains for individuals.

Bing Brunton's team, with John Tuthill, simulated a fruit fly ventral nerve cord (4,000 neurons controlling two front legs). A "pruning study" then identified a minimal circuit of just three neurons - two excitatory (E1, E2) and one inhibitory (I1) - sufficient to generate the basic walking rhythm.

Brunton highlights a successful model-driven prediction: a previously unstudied neuron from the central brain made a fly leg tap when activated by a laser. Experimental validation confirmed this prediction, demonstrating the model's predictive power beyond simply fitting existing data.

Bing Brunton's lab aims to create "digital twins" of animals: biologically interpretable simulations of the nervous system within a biomechanically realistic body and virtual environment. This allows studying complex feedback loops and predicting behaviors human intuition cannot grasp.

Brunton critiques "digital sphinx" models achieving behavioral fidelity without biological accuracy, demonstrating it by training a C. elegans connectome to control a fly body with reinforcement learning. This shows deep learning can mimic behaviors even with mismatched neural architectures, emphasizing meaningful biological interfaces.

Brunton envisions using embodied animal models to understand nervous and musculoskeletal system interactions, especially for injuries like spinal cord damage. Such models could provide insights into long-term adaptations and help design better therapeutics or rehabilitation strategies.

Keon notes that Anthropic's Dario Amodei met with the White House regarding the alleged cybersecurity threat posed by advanced AI models, referred to as 'Mythos,' with Toeer suggesting such claims are a tactic by security companies to sell products.
