I exclusively use CLI, it’s not ego at all, I simply find typing what I want to be quicker than clicking buttons. I’ve written a bunch of aliases to automate my common workflows.
When I need to help a colleague who’s made a mess of something, I can easily give them the command to fix it rather than finding the right options in their GUI of choice and it’s often because of some broken abstraction in the GUI they got into the mess in the first place.
