Watson is actually sort of boring stock-in-trade stuff for IBM when looked at through a certain lens. (Not that it isn't noteworthy or anything.) The phrase "IBM researchers have..." used to be attached to things like atom-by-atom manipulation (the atomic IBM logo was the PR piece), superconductivity (Bednorz and Müller)... things that might one day mean a whole heck of a lot, but in the meantime amounted to allowing some very smart people to piddle around trying interesting stuff. There was always hope that some technology might fall sideways out of the work, but the IBM of the day was significantly less attached to success. Pre-PC Revolution, they were in a position to afford it; Gerstner's IBM could not.
