Why does HN continually talk about technology that's decades old yet we have no proof that it works. Has Watson ever done anything? Is it used anywhere? I don't want a PR puff piece. Don't want theories. Don't want, I used it for a week. I don;t want to know what you claim it can do. I want an article or youtube from an independent person who's used it in the field for a year and confirms it works at all. How about we start there. And FYI Watson cheated at Jeopardy. It couldn't even do that properly.
