Indeed, some tech is based on things like physics, math, chemistry, manufacturing, and so forth. We've figured out how to have people managing a tech business, who couldn't grasp all of the disciplines that go into the tech. The danger with any technology is that it will start extracting rent from your business if you don't understand it. At the very least, I'd advise any manager to read The Mythical Man Month, which I think is still fresh after nearly half a century.
