Watson, IBM's supercomputer made famous three years ago for beating the very best human opponents at a game of Jeopardy, now comes with an impressive new feature. When asked to discuss any topic, it can autonomously scan its knowledge database for relevant content, "understand" the data, and argue both for and against that topic.

Watson's DeepQA is arguably the world's best computer system at natural language processing by a wide margin, which is an extraordinarily complex field of artificial intelligence. Perhaps the major difficulty in understanding human language is the lack of "common sense" in today's computers. For all its number-crunching power, Watson cannot "understand" the questions it is asked, at least not in a traditional sense. The way in which Watson answers questions is closer to symbol manipulation than to the way you and I understand and process information, but the end results are often impressive.

Watson looks at the question it is being asked and groups words together, finding statistically related phrases. Thanks to a massively parallel architecture, it then simultaneously uses thousands of language analysis algorithms to sift through its database of 15 terabytes of human knowledge and find the correct answer. The more algorithms find the same answer independently, the more a certain answer is likely to be correct. This is how, back in 2011, it managed to win a game of Jeopardy against two human champions.

In a presentation at the the Milken Institute Global Conference, IBM senior vice president and director of research John Kelly III demonstrated how Watson can now list, without human assistance, what it believes are the most valid arguments for and against a topic of choice. In other words, it can now debate for or against any topic, in natural language.

In a canned demonstration on stage, Watson was asked to present arguments for and against the sale of violent videogames to minors. After scanning Wikipedia for relevant information, Watson answered:

"I would like to raise the following points in support of the topic. Exposure to violent videogames results in increased physiological arousal, aggression-related thoughts and feelings as well as decreased social behavior. In addition, these violent games or lyrics actually cause adolescents to commit acts of real-life aggression. Finally, violent videogames can increase children's aggression.

On the other hand, I would like to note the following claims that oppose the topic. Violence in videogames is not causally linked with aggressive tendencies. In addition, most children who play videogames do not have problems. Finally, videogame play is part of an adolescent boy's normal social setting."

The answer wasn't just a mindless collage of sentences copied from various Wikipedia articles. Rather, in just a few seconds, Watson searched its sources for relevant information, scanned for arguments in favor and against the topic, selected what it believed were the strongest arguments, and then constructed sentences in natural language to illustrate the points it had selected.

For a computer that doesn't actually "understand" the questions it is being asked, this is a truly impressive achievement.

IBM believes that the technology behind Watson will prove very valuable in dealing with the exploding amount of information that we're currently facing. A fully automated system that can process huge amounts of data, extract information and find answers with a high degree of confidence could prove useful in a number of fields of human endeavor.

For instance, the system could have important applications in the medical arena. Oncologists could take a DNA profile from cancerous tissue, compare it to healthy tissue of the same organ, extract the mutations, and then use Watson to search the entire medical literature to find which specific combination of drugs will be best at targeting that specific mutation affecting that specific organ.

Back in February, IBM also announced it intends to use Watson to help countries in Africa find the answers to their development problems, with a focus on healthcare and education.

Watson is built on commercially available 750 Power servers, because IBM aims to market it to corporations in the future. The hardware to operate Watson at its minimum system requirements currently costs a relatively modest one million US dollars, but the price is expected to drop in the coming years.

The video below shows the new debating feature in action. The presentation starts at the 35 minute mark, the canned demonstration 46 minutes in.

Good bye to tech support and telemarketing in 10 to 20 years as soon as this is perfected and sold to global corporations.

About time, now we can replace lawyers with Watson.
Many years ago science fiction author Isaac Asimov wrote a story called "Franchise" in which the fictional supercomputer "Multivac" determined the result of the 2008 US presidential election by questioning a single voter, Norman Muller, and using the data obtained to calculate the likely outcome of a "full" election.
Although initially reluctant, after "voting", Muller is very proud that the citizens of the United States had, through him, "exercised once again their free, untrammeled franchise" – a statement that is somewhat ironic as the citizens did not actually get to vote.
How long till reality catches up with art?
The couple times I have contacted tech support via email the human rep grabbed /maybe/ 2 or 3 keywords out of scanning my email and sent me a canned response. Watson couldn't do worse. Ditto for calling a company on the phone and trying to navigate their phone tree to do something simple.
In the corporate world there is a big need for people making decisions to be able to analyze a lot of data and/or send subordinates on tasks of fetching specific data points to assist a decision. I could see a lot of uses for Watson.
My experience in IT and processes leads me to believe that jobs are always at stake. The guys on top are sociopaths. I know them, and used to work for them.
Clever IBM marketing, but I'm surprised how the entire world swallows it.
"Listing arguments" is hardly the same as "debating". Debating involves managing dialogue, tracking the opponent's train of thought, and counter-attacking. Listing arguments is basically an exercise in entity extraction, which has been around forever.
A canned demo without a possibility to inspect results means it's just as ready for the real world as the rest of Watson.

Now if it could examine the arguments it discovers, evaluate the supporting data for them in literature and statistics and alter it's knowledge base to reflect which side is probably correct (while allowing the possibility for new changes) it would be an even bigger deal.

I guess Dario doesn't have the skills that Watson has, because he chose not to google the Watson's "arguments". If he did, he would easily find out that all of them were copied verbatim from various Wikipedia articles (sometimes old versions, because they used an offline copy). Here they are:
and CON
Not to mention the fact that pro arguments 2 and 3 ignore the context of the sentence. In 2 Watson says exactly the opposite of what the author said (Watson ignores the start of the sentence: "However, it is highly debated whether...". In 3 the end of the sentence is ignored — "but that parents moderate the negative effects." Also, 3 basically repeats what 1 and 2 said.
Arguments con 2 and 3 are not logically sound.
