Yes, electromagnetic waves connect the cosmos as we know it, but so does gravity which is not recorded by cameras. We have reasonably good eyes well suited for life in the Savannah during daylight, and a brain that can make incredible images out of what we see, but that does not mean "man captures light in a most balanced and integrating manner.". Cameras are certainly no black boxes to those who make or service them, and the fact that case and shutter let only those few photons in that are meant to be recorded does not make a camera "secret and genital". A video camera is quite illuminated inside while it records, BTW.
And that's one of the weird things in many of these "philosophy of photography" tractates. Authors go through great length to derive a very solid train of thoughts, including lingo that is nearly impenetrable to humans not trained in that subject, and then base their whole train on thoughts on a very fuzzy image of modern physics, brain science and aesthetics.
