yea, we have quite a while before we will see a cpu that can match the complexities of the human brain.
A lot of people had arguments of how fast the human brain can calculate (as in math problems or some nonsense). The brain was not designed to do math problems alone. It is a highly advanced multiple core, multitasking unit that hears, sees, feels, smells and understands this input. At the same time, the brain can also perform mundane tasks such as solving math problems. Think of how many operations, how much raw binary data, it would take to process all of the information in a single given instant of your life. Human perception is FAR beyond any computer in existence.
