How tech will (and won't) replace your doctor | Zack Abbott and Dhruv Khullar

Science and technology are fundamentally reshaping the human experience, necessitating a shift in how we approach health and medicine. Moving beyond the current obsession with quantitative metrics like sleep trackers, true health relies on a qualitative understanding of one’s own body and subjective well-being. Genetic engineering, exemplified by recent breakthroughs in curing sickle cell anemia, offers transformative potential, while artificial intelligence will likely automate routine clinical care, allowing doctors to focus on complex, value-based decision-making. Furthermore, the human gut microbiome functions as a complex, plastic ecosystem that demands diverse fiber intake to maintain balance. Ultimately, the challenge lies not in what science can achieve, but in determining the ethical boundaries of these interventions, particularly regarding germline editing and the deliberate evolution of food systems to prioritize nutritional density over aesthetic appeal.
