The implication that something that creates something else is superior to the thing it creates is a fallacy. There is no inherent relationship between them whatsoever - it is only measurable via direct measurement of performance. The claim that "humans created the Go engine makes them superior" is exactly the same amount of logically incorrect as the "it's a machine so it's superior" claim.
If your claim that creating something means superiority held true, Lebron James' dad must be better than him at basketball. And I know that's a ridiculous claim. But it's logically equivalent to your own.
