Tech is a weirdly wide term. Does it only include IT? Engineering? Astrophysics?

A lot of work is “tech” as in technology related. It is inevitable to be clueless about a lot of technology, even when being the spearhead of development in one specific field.

Meanwhile you don’t need to tell the guys at the car-shop about programming, but they most likely know more about every non computer part of the car you just brought to them for repairs, because you were clueless about where that weird sound comes from.
