This guy seems to be stating a made up tautology due to the fact that he is redefining eng.

According to this guy we do mostly design and specification. Of course then you could say the Bay Bridge, the Space Shuttle, the 787 and every product that requires a long design and exploration pathway is not engineering. I don't know of anyone at Google who considers dev the same as mechanical engineering. It's more of an exercise in managing complexity, mathematical optimization, social science and design theory. But we sure as heck aren't designing for the knowns required to do what this guy defines as engineering.

But so what?
