Decline of Stack Overflow user engagement is more nuanced than it seems. The sharp activity drop in #knowledge-sharing platforms has sparked concerns re the sustainability of #GenAI. If LLMs depend on human-generated data but reduce content generation, are we hitting the so-called #peak_data? 1/n

AI and stubborn human collaborators: a problem or a solution? 🧵 🪡 A recent paper published in JAMA ON reveals a paradoxical pattern in medical diagnostics: GPT4 achieved 90% diagnostic accuracy working independently, surpassing both unassisted physicians (74%) and LLM-assisted physicians(76%). 1/5

New Preprint: Scalable adaptive network intervention for multi-agent systems using RL+Variational Auto Encoders (VAE) Past research has shown that the network structure of agents interactions influences system-level behavior, thus can be used as an effective system governance intervention. 1/n

This is the issue that the new cognitive turn in behavioral econ has to resolve head on. Is the dimensionality of factors that the new frameworks are introducing going to be so high to make them vacuous? 1/n
