This is a clever but specious answer. It is interesting that if a computer significantly surpassed human intelligence it would be distinguishable from a human. And my presumption is that once computers achieve human-like intelligence they will then quickly surpass human intelligence because they will be able to rapidly access so much knowledge. I am reading a book my father told me to read a number of times; the first time was probably 45 years ago.A book by David Rappaport, published in 1951. He translated some European texts. One chapter is about some cognitive tests that Karl Buehler conducted. He asked people some to figure out the meaning of some sentences and then asked them to give an account of their inner experiences in solving the problem. "Besides thoughts, yet other knowledge is present in our thinking. For instance, we know whether or not we are on the right track, whether or not we are approaching our goal, whether the thought occurs to us for the first time or derives from our memory; we may know even where we have picked it up; we know how it is related to the one preceding." Here is an example of one of the problems he asked, but they are not all like this. This one is particularly appropriate for these kinds of groups: "'We depreciate everything that can be explained.'" If a younger, studious person read that he might take a few seconds to understand it. What process of mind would he have to go through. Although our introspective thoughts on how we came to some conclusion or understanding are not reliable, they are indicative that there is more going on than just looking up some interpretation of words and finding the right encyclopedia reference to find the most likely answer and it is indicative of some more elaborate mechanism that a deep neural network. But this kind of question might culminate in explanations of how we can work out how the words of a sentence are related and how they shape (or direct) meaning and how we can solve problems. It is this construction mechanism which will give us insight to more human-like intelligence, even if the answers are not entirely correct.
