And to bring it back so the moderator doesn't yell again, as the System P is improved to handle this better, it will eventually be integrated into the z196's successor, which will allow using each technology in their sweet spot. There has been some talk about Watson working in medical diagnosis. Forgetting HIPPA issues for a minute, imagine having a process of using medical billing procedure codes to feed into Watson to look at trends, or assist in recommended procedures.
