Some other comments here are good but I'll point out that what most people don't understand is that "Watson" is the name of a marketing umbrella, not a technology. Essentially, almost anything at IBM that had AI/ML smell to it got tossed into the "Watson" market bucket. This allowed IBM to push a huge set of technologies that they could then customize and build services around, for a large fee of course.

The problem is that most of the AI/ML technologies IBM used were stock, off the shelf, often not even state of the art. You could literally go to a github page or use scikit_learn out of the box to get equivalent or better performing models without being tied to IBM's proprietary, consultant heavy, solutions.

The marketing of Watson, tied to the Jeopardy performance, made people think it was the first coming of AGI -- a kind of Skynet moment. It was really just a cobbled together basket of unintegrated, nothing special, industry bog standard AI/ML stuff.
