Letter to My Younger Self
Bryan Johnson, founder of Kernel and Braintree, delivers an emotionally charged address to his younger self—a 24-year-old who was chronically depressed and trapped within the protective “ninjas” of Mormon belief. Johnson outlines seven priorities for human flourishing: recognizing our cognitive impairment, building systems that don’t render humans obsolete, identifying “game-over” problems, embracing AI as a partner, becoming future-literate, updating belief systems rapidly, and making radical cognitive improvement humanity’s top priority. He argues that whether one remains Mormon, leaves, or does both, the work of expanding human cognition cannot be outsourced to an afterlife—it must begin now.
