>, SQL teaches you [...] Without any wrapper masking low-level logic.

I understand the point you're trying to make, and yes, it does seem like SQL is "low-level" from the perspective a wrapper like ORMs or a GUI db browser tool with menus for filtering data.

But it's also worth remembering that SQL itself is a high-level wrapper that hides the lower-level C/C++ code of the db engine that has the loops that iterate through b-trees, 8k data pages, memory blocks of the buffer cache, etc.

And C/C++ itself is a high-level wrapper that hides the logic in lower-level Linux o/s system calls that manages RAM and disk i/o.

And Linux itself is a high-level wrapper that hides low-level device drivers like SATA/SSD memory-mapped IO ... and so on and so on.

Depending on the type of app, you can ignore all the lower levels and just work at the abstraction level of higher-level wrappers.
