> id say most people i’ve worked with start caring to learn the shell and dig into the os more around year 8 of their career

That sounds tragically late to me. It represents a serious failure on the part of those who know and love the command line to make it accessible to newcomers, imo.

nah it just shows how the valuable abstractions have moved up. i bet this 8 year mark will only get later over time until it disappears

Level of abstraction is largely orthogonal to the GUI/CLI divide, though.

nmcli is more abstract than ip+iw+wpa_supplicant, but it's no more or less abstract than any GUI network configuration widget.

The output of ls is no more or less abstract than the contents of a directory as displayed by a GUI file manager. It's the same metaphor and the same information displayed in two different formats.
