I think it is true if you put proper emphasis on the word "comparatively". It's maybe better to state it as "It is much harder to make computers control movement as well as a toddler, than it is to make them exhibit adult level performance on intelligence tests." Or, to put it another way, the hardest part about teaching a computer to do a classical IQ test is how to hold the pencil, not how to find the right answers.
