What you'll see is Watson-like computers drudging through all the raw data -- the analytics -- and making sense of the common, recurring patterns of info there. For example, all those tech support jobs we sent to India a decade ago won't be needed with Watson on the line, especially if Watson can login and mirror your actions. For anyone who has a job that requires analyzing vast amounts of info -- a doctor who needs evidence that a symptom is true rather than a diversion from a proper diagnosis. (Someone like Gregory House, MD, wouldn't need his staff anymore, so they should probably be looking for other jobs soon.) For financial analysts and investors who are tired of getting ripped off by humanoids (and no governments with enough guts to police them).
As long as Watson's offspring don't become sentient and discover the nuclear launch codes, we should be fine.
