Is a Machine Realization of Truly Human-Like Intelligence Achievable?

Even after more than a half a century of research on machine intelligence, humans remain far better than our strongest computing machines at a wide range of natural cognitive tasks, such as object recognition, language comprehension, and planning and acting in contextually appropriate ways. While progress is being made in many of these areas, computers still lack the fluidity, adaptability, open-endedness, creativity, purposefulness, and insightfulness we associate with the supreme achievements of human cognitive ability. Reasons for this and prospects for overcoming these limitations are discussed.
