Director of Emerging Watson Technologies at IBM, Alexa Swainson-Barreveld speaks about what Watson is and what its benefits are. Watson began as a research project but has evolved into an IBM Business Unit. Unlike other technology, Watson has the capability to learn as humans interact with it. It enables access to expertise, since it knows everything from finance, to medicine. Alexa assures us that this machine will not take over; it will simply work with human interaction to make things better for the world.
