Centuries of medical practice led to a knowledge explosion, fuelling unprecedented advances in human health. Breakthroughs in artificial intelligence and low-cost, contactless sensors have given rise to an ambient intelligence that can potentially improve the physical execution of healthcare delivery. Preliminary results from hospitals and daily living spaces confirm the richness of information gained through ambient sensing. This extraordinary opportunity to illuminate the dark spaces of healthcare requires computer scientists, clinicians and medical researchers to work closely with experts from law, ethics and public policy to create trustworthy ambient intelligence systems for healthcare. https://www.nature.com/articles/s41586-020-2669-y
