In a previous post, I linked to an IBM executive who claimed that Watson’s success on Jeopardy! might revolutionize the legal profession.  Gary Kasparov, the chess champion who was defeated by IBM’s Deep Blue in 1997, makes an interesting observation over at the Atlantic:

My concern about its utility, and I read they would like it to answer medical questions, is that Watson’s performance reminded me of chess computers. They play fantastically well in maybe 90% of positions, but there is a selection of positions they do not understand at all….A strong human Jeopardy! player, or a human doctor, may get the answer wrong, but he is unlikely to make a huge blunder or category error—at least not without being aware of his own doubts. We are also good at judging our own level of certainty…but I would not like to be the patient who discovers the medical equivalent of answering “Toronto” in the “US Cities” category, as Watson did.

It would be ironic (in the extreme!) if what saved the legal profession from being taken over by computers was lawyers’ own humility.  In a world where machines can process far more data far faster than human minds, perhaps our weakness is also our greatest asset:  we know our limits.
