Can a computer be complicated enough to act like a human being? No.
This is not a debate whether a computer is smarter than the brain because it is. A computer is basically able to access all of the information known to man through the internet. As someone brought up in class, the computer doing a diagnosis on a specific cancer patient was able to find an unconventional method of treating the cancer based on a specific part of the DNA that was able to save a life that a human doing the diagnosis most likely would not have found. However, this computer was merely using an algorithm to determine key words that may have matched with an article. If the computer was then asked why this cancer treatment would work or any question beyond what the search came up with, that is where the computer falls short of the brain.
It was brought up in class the idea of intuition. If you had to pick between a red car and a blue car you would be naturally inclined to one over the other. You do not really know why, you just like one color more than the other. This is something that I do not believe a computer will be capable of knowing. Where I might pick the blue car, someone else in the exact same situation may choose the red car. There is not some generic algorithm that every human uses to decide what car to choose, they just do. After playing around with CleverBot in the last class, my group asked what nationality the bot was and the bot replied, “Canadian.” A couple questions later the same question was asked and the bot replied, “I do not have a nationality.” Yes, this is not the most advanced computer system out there and there very well could be a computer out there able to return the same answer but overall, it seems that a computer would be too unreliable. There is something about the human brain that a computer will always lack.
This may be personality. We read in the article “Robots that Care” that the robots used to help patients in their homes that they were able to develop a personality and were able to respond and communicate with the patients in certain ways based on their personality. But a human using an algorithm created this personality. It is difficult to distinguish between the robot actually thinking for itself or just following some programmed code appearing to be thinking for itself. Humans have a personality that is not programmed, it just is.
I do not want to rule out the possibility of a computer being as complex as the brain because that would be an amazing feat but I lack confidence. A computer can be programmed to be randomized but will not think randomly on its own. The human species is unique and I don’t think the brain is meant to be robotically made. It can be replicated but never truly made.
