without enhancement some problems are just to hard for humans.

Without the enhancement of a computer or at least external memory like pen and paper, can you compute the n-th roots of pi to arbitrary decimal places? I can't, so it seems plain that Dawkins was correct. But it's a mighty big jump from there to "and there are processes in the universe which no constructible tools could ever let us explain, even in principle".

Humans with our enhancements haven't yet found any aspect of the universe which we have good reason to believe will always continue to escape explanation. That lack of evidence is weak evidence in favor of nothing remaining permanently and necessarily mysterious.
