This might be a naive question, but here me out. Do we really know what the difference is between statistics and the capacity to think? Is "true understanding" rather a continuum of sophistication from a simple adder to Albert Einstein? My point here isn't "if it quacks like a duck...", but more so that while we are talking about intelligent apparatus we should be comparing apples to apples, and not say "this is a mere engine and that is a living brain".
