But a brain can not be as proficient as a computer at this function. A brain is subjected to immaterial input that may interfere with a defined algorithmic undertaking. Fatigue, the subconscious, prejudice, poor memory, and, possibly, our genetic composition, may unduly influence the defined algorithm. After all, "to err is human."
A computer is unaffected by such human traits. Computers, properly programmed, do not err. With relevant input, they will function far better - unaffected by memory issues, emotions, or prejudice. A computer's memory is essentially boundless. The retrieval of required algorithmic facts occurs at almost lightning speed. A computer can, therefore, outperform the human brain! "Jeopardy" has so demonstrated.
I am a physician. A physician's job is to obtain information from a patient using various techniques, then to input the accumulated data into his brain, and finally arrive at a diagnosis via mental algorithmic analysis. But we physicians are human! We err. We err as a consequence of these human variables.
I feel quite certain that a medically sophisticated Watson (Dr. Watson, I presume) will outscore the diagnostic acumen of the physician in the near future, and will become the physician's most valued "partner." Dr. Watson will "outdiagnose" all of us. Not only outdiagnose - but "outmanage" as well, because the management of a medical problem is also an algorithmic conclusion. We physicians won't accept Watson, at first. Like so many advances in medical management, we will have to be dragged to it "kicking and screaming," but eventually accepting it in the end.
But the human brain is still the master at innovation and new ideas in research and development.
And, we still need the flesh and blood providers of medicine to furnish, through their "art," the very important human functions of compassion and concern, which, even today, remain, arguably, the primary content of the doctor-patient interaction, and among the most crucial forms of therapy.
