I thought one of Watson's main projected uses was healthcare. Isn't Google's stake in healthcare via DeepMind actually make them competitors in that sense? Unless I'm missing something here, I have not researched Watson a lot.
I don't mean this as a disparagement, merely as a dispassionate observation. Doctors need alerts about contra-indications of drugs they and their patients' other doctors have prescribed more than they need AI-derived diagnoses, for example.
