Excellent article on an exciting topic! I wonder how we will navigate the ethical/legal ramifications of care based on digital twinning. For example, if a digital twin shows poor response or side effects to a promising treatment for a patient with serious disease, and the treatment is therefore withheld. We can assume that a digital twin will never 100% replicate the patient's physiology. Should the patient's condition worsen, would they have grounds for litigation against the physician or the operator of the digital twin due to withholding the treatment? What would the informed consent look like when a patient uses a digital twin?
