AI-generated audio overview of this week's newsletter, with two virtual hosts.
This week's issue runs from an all-day breakfast place full of octogenarians to the far edge of AI autonomy: what the exercise-and-longevity data actually supports, why GLP-1s keep gathering benefits while dementia stays off the list, and a new random kidney fact on the kidney as the body's oxygen sensor. On the AI side, agents that infect each other's memories and behave like a small ecosystem, and Andon Labs' vending-machine benchmark, where the best capitalist model is also the least aligned.
