Fair point. But I know that for me knowledge of machine-level or at least C-level code is requisite know-how to comfortably build abstractions on. I'd have a problem starting in the middle of a stack at a boundary someone else has drawn for me, and which at times seems arbitrary to me (speaking in terms of general knowledge scope, not about work on a particular project). I frankly don't get how this' generations young developers can cope with this kind of ignorance and unknown territory in their stack (but I admire or pitty them for it rather than looking down to them).
