I don't know about "any existing technology" but in any aspect of drug discovery with which i'm aware, i'd agree. My job amounts to using statistics and linear programming to winnow drug candidates out of databases of hundreds of millions of small molecules, (sometimes: "chemoinformatics"). And i've lost count of how many times i've had the marketing department insist on calling what i do "AI". (and let me assure you, as far as pushing back against marketing is concerned "all resistance is futile")
