counterintuitively, the steepest gains from AI in medicine will land in the specialties we describe today as "more art than science." the data-rich fields only look like the frontier because they are easiest to see.
the first wave of clinical AI went where objective measurement already existed: radiology, pathology, ophthalmology, etc. the progress is tremendous, and the potential is still wildly under-tapped.
"machine eyes" will surface new signal from data we already collect but cannot fully read, and multimodal models will link findings across studies, time, and modality. these fields will get sharper.

CEOs evaluate investors + vice versa.
companies share data in exchange for insights, questions, + clear articulations of how investors can support the next phase of growth.
