Bryan Johnson posted that understanding Kate through her continuous biodata is akin to mechanistic interpretability — opening a black box to find the circuits explaining behavior. He notes that after 40 days of behavioral consistency (sleep, diet, exercise), her erratic hormonal swings lessened by over 30% and stabilized. Miles Brundage amplified it with the quip "they did mech interp on a women."
