I have pondered over this for a while. When we say human intelligence or "true intelligence" as you say it, the fact is, it is full of irrationality and errors. I believe that computational AI will go farther than we can imagine for the simple reason that we cannot process information the way a computer can; its relentless.
Insisting that computer intelligence resemble human intelligence is probably the characteristic that the future will mock the most, like the way we mock primitive overdecorated Victorian machines.
I too have been pondering this and I think the field is lacking the concept of artificial _imagination_. Maybe intelligence = knowledge + imagination, and since we already have massive artificial knowledge (wikipedia for example), AI is just missing the imagination to comprehend all this data.
