Once a reliable and efficient system of AI is developed, computers will quickly overtake human beings.
Think about it, most human beings spend 6-8 hours per day sleeping and 8-10 hours per day working in repetetive jobs. This means that for 14-18 hours per day, most humans do not learn anything new or useful. In their free time, most humans do not spend all of it learning new skills or acquiring new information, we spend it in leisure pursuits, having sex, watching telly, listening to music, killing brain cells with alcohol, eating etc. Also, as we get older, our ability to learn new skills and adapt diminishes due to the deterioration of our bodies and brains and we have a relatively short lifespan. The average human being is severely limited in it's ability to acquire knowledge.
A computer with real AI, on the other hand can acquire new knowledge and skills and adapt, 24 hours a day. If it is properly maintained, it's ability to learn and adapt will not diminish with age - quite the opposite, with regular upgrades it will improve it's ability to learn and could, theoretically function indefinitely. A properly maintained computer with advanced AI could absorb and process the entire sum of human knowledge fairly quickly. Computers can already perform tasks that most human beings cannot and a damn sight faster than those who can.
A lot of this, at the moment, depends on us to develop the technology but once the computers learn to do this for themselves (and they will - one day), they will no longer require input from us. I think 2029 is a tad optimistic but I'm convinced it will happen in the next hundred years or so. If Moore's law persists, as it has done for the last 40 odd years, for another 40 years, computers will be hugely powerful machines, well capable of overtaking the average human being. The brain may be many times more powerful than computers at the moment but even the most intelligent of us only use a tiny fraction of it's ability - a computer can use all of it's resources, indefinitely.
