Would you like to play a game?

No, not Joshua. Maybe it is SkyNet. In any case, the Jeopardy playing computer, Watson, is freakishly good at the game. As of this evening, he/it is leading Ken and Brad by over $25,000.

According to Wikipedia,

"Watson is made up of a cluster of ninety IBM Power 750 servers (plus additional I/O, network and cluster controller nodes in 10 racks) with a total of 2880 POWER7 processor cores and 16 Terabytes of RAM. Each Power 750 server uses a 3.5 GHz POWER7 eight core processor, with four threads per core."

It is one thing to store all the world's knowledge (295 exabytes), but it is another to access it in response to contextual clues in natural language.
