What even is "Watson"? It looks like it's just IBM's AI department, but they talk about it as if it's a single program. I know that the Watson that's being applied to medical diagnoses is at least somewhat related to the Watson that was on Jeopardy, but this seems like a different program entirely. Why this weird pretend game that these tasks are all being done by the same general AI? As theatrics go, goofy branding is a lot less interesting than being good at Go.
