How Smart Can a Smart Machine Become?

Perhaps one way of addressing the measurement of machine intelligence would be to mimic the way we measure human intelligence. Although the debate around what "intelligence" actually means has by no means been resolved, most psychologists would agree that the standard IQ tests measure "something" that has predictive power when comparing cognitive results across a human population, or predicting an individual's future performance in a range of cognitive tasks. Perhaps then one could devise a test that explores a number of agreed areas of cognition - for example knowledge, memory, comprehension, vocabulary, etc. - then draw a set of questions that measure "machine IQ". But there are several problems with this approach. Firstly, it is too anthropocentric. Secondly, an IQ test is a snapshot of a subject's cognitive ability.
