OK, by way of acknowledgement of splittingTimes' downvoted clarification, it seems the phrase "the boundaries of our perception are set by basic laws of physics, and that we reach the limits of what is possible" comes verbatim from a text in which the context is clearly the detection of photons. So it wasn't intended to be a claim of optimality for the human perceptual apparatus in general.
