Your anecdote actually reinforces my comment. See my comment below for context - https://news.ycombinator.com/item?id=37378513

Your "Amplifier" is more like what is known as a "Field Applications Engineer" in the Embedded industry i.e. somebody with enough Domain/Technical/Marketing/Sales skills fulfilling a tangible need for the Business. They are more a "Business Process Optimizer" than a "People Amplifier"(a term i made up :-) who i define as somebody who can spark creativity/insights/viewpoints etc. which push others forward in their problem-solving endeavours. It is not merely removing hurdles/book-keeping/time management/liaisoning but an active role involving discussions/brainstorming/idea generation. This cannot be done without bringing some expertise to the table relevant to the problem at hand.
