Watson is also backed by a huge corporation, which makes it easier to surmount obstacles like "but doctors don't like competition."

On the other hand being a huge corporation makes it harder to surmount "relying on marketing hype to inflate the value-added of the product."

At any rate, the company I work for relies heavily on Cognos and the metrics there seem pretty arbitrary--Hocus pocus to conjure simple numbers so directors can pretend they're making informed decisions and not operating on blind guesswork and vanity....And to rationalize firings, raise skimpings, additional bureaucracy and other unhappy decisions.*

*Come to think of it, "intelligence" or not, Cognos does emulate homo sapien psychology to a high degree of approximation.
