Forget AI Winter—those, right there, are fighting words. Though Watson was also unveiled with an unabashed PR stunt—its quiz show evisceration of two human Jeopardy champions in 2011—the system has since graduated to deployments with world-tilting implications. Less interesting is IBM pushing Watson as a call-center rep, using its natural language processing chops and rapid access to a teraflop of internal data and millions more online files and records to interact with customers. But Watson is also playing Sherlock, diving into medical records, imaging results, millions of pages of journals, and other data to provide possible diagnoses and treatment options to doctors. The system is being deployed in this capacity at multiple medical centers, including the MD Andersen Cancer Center at the University of Texas, as part of its "moon shot" program to cure leukemia outright. Watson will serve as a diagnostic assistant, grinding through scattered research, patient, laboratory and other databases to find meaningful connections, and even draw conclusions regarding treatment and candidates for clinical trials.
