If Iago was with us, you just know what he would say!

Anyway, here's what I have to say:
That passage in the grand scheme of things is not that complex. If you want complexity, don't look at a five part fugue, instead look at a Fourier decomposition of someone talking. For a work that's supposedly too complex to hear all at once, it was still written, and people can see it in writing, and people can perform it. That doesn't exactly seem transcendent to me.
Complexity is not the same as profundity. What should be admired in great music is beauty, not complexity.
