content: I think the key is in knowing the meaning of the word 'hubris'. Humans in their hubris imagine that equations they learned in engineering college are the be all and end all of things like "efficiency". With this presumption they remain within a narrow idea of the "possible". You will notice the increase in efficiency - 700% by the claim. Even if this is overstated - it may be - it is a considerable advance over standard practice. The angle, of course, is only part of the story. A good analogy is the idea that the present state of materials science is all that can be said about the subject. By that sort of 'reasoning' the study of spider silk and how it can inform the subject is not "possibly new".
