my story 🚀

Having a great time outdoors

🍂 The first fall we ever spent in Austin, I thought to myself that it was like extra innings of summer. As we approach our 3rd anniversary here, it still feels that way!

Are self-driving cars already safer than human drivers? “For this story, I read through every crash report Waymo and Cruise filed in California this year, as well as reports each company filed about the performance of their driverless vehicles (with no safety drivers) prior to 2023.” I look forward to my first ride in a self-driving car, which might be soon! ~ learn more

Why QED is doubling down on Kin. A laudatory memo from a recent investor in the Chicago-based insurance startup Kin (disclosure: I’m lucky to be a small investor as well). “The difference between these financial metrics is so stark that we believe Kin will be the defining company of insurtech 2.0. Whereas Lemonade, Hippo, and Root prioritized growth over control, likely believing that risk would normalize at scale, Kin’s model is based on a real understanding of insurance from the inside out.” ~ learn more

An ‘inverse vaccine’ that can reverse autoimmune diseases. Outstanding result! “A new type of vaccine developed by researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) has shown in the lab setting that it can completely reverse autoimmune diseases like multiple sclerosis and type 1 diabetes — all without shutting down the rest of the immune system.” ~ learn more

Single-dose psilocybin treatment for major depressive disorder. A randomized clinical trial of 104 adults, including a placebo group (I wonder if those people quickly figured out which group they were in?). In any case, the results of the psilocybin group look strong. “The primary outcome was change in central rater–assessed Montgomery-Asberg Depression Rating Scale (MADRS) score (range, 0-60; higher scores indicate more severe depression) from baseline to day 43.” The average for the intervention was -12.3, vs -2.3 for the control. ~ learn more
