AI is a business model stress test

AI commoditizes anything you can specify. It can't commoditize what you have to operate.

🧠 New paper by Huang et al.: By using #pharmacological #fMRI and dynamic #connectome-based #PredictiveModeling, they show how #cortisol reshapes whole-brain #NetworkDynamics during emotional memory encoding. Trial-level analyses reveal distinct but increasingly integrated #arousal and #memory networks under #stress, supporting a hormonally driven "memory formation mode".

Fig. 2. Analysis design. (A) Schematic of the trial-level phase synchrony extraction approach. (B) Schematic of dCPM. Edges that are significantly correlated with memory/arousal are selected. A linear model is then trained to predict memory/arousal on the left-out trial. This model is separately applied to all four study conditions (pill × emotionality) to yield four predictive networks. R, remembered.

And other systemic changes other than air pollution too, ofc

Like: Become a member of an organization, talk positively about good policies in your friend group, going to a local hearing and speak in support of new bicycle infrastructure, donate and/or volunteer for a candidate, etc. For your health

This thread was inspired by the latest episode of the podcast Maintenance Phase, on the seed oil hype https://maintenancephase.buzzsprout.com/1411126/episodes/17731905-seed-oils
