I see your point clearly, and it's a good one. However, consider the following counterargument: the exact same thing could be said (and was said) extensively about low-level programming concepts such as registers, later pointers, memory allocation, etc. It was essential for every software engineer to master... until it wasn't. Same with lower-level OS fundamentals. Same thing earlier with pre-PC hardware.

We've come full circle with the present-day cloud providers like AWS. 15 years ago they started as simplification, but today they are boxes of 200+ specialised building blocks that are anything but trivial to put together. A human specialist has to be involved. But why? This complexity is completely artificial, its sole purpose is to keep their customers locked in. This must and will be solved with better tooling. That's what we are trying to make.
