Great roundup of AI applications in healthcare. What's striking to me is how much of the AI value in diagnostics comes from pattern recognition across massive datasets, which is basicaly what companies like Veracyte have been doing with their genomic classifiers for years. Their Afirma test for thyroid nodules uses machine learning to analyze gene expression patterns and predict which nodules are benign versus suspicious, helping docs avoid unnecesary surgeries. That risk stratification use case you mentioned is huge. It's not just about detecting disease, it's about understanding which patients actually need aggressive intervention versus watchful waiting. The personalized treatment piece is where I think the next wave happens. As you move from diagnosis to treatment selection, AI can help match patients to the right therapy based on molecular profiles. Veracyte's doing this with their Decipher prostate cancer test that predicts which patients will respond to radiation, hormones, or active surveilance. The infrastructure you need to make all this work at scale is interesting too, labs, data pipelines, clinical validation, reimbursement. It's not just an algorithm problem, it's a whole ecosystem challenge.
