During my IT career I met developers and IT DevOPS who literally could not start a Fusion VM's on a MacOS by clicking on the button "Start the VM",because they were too used to another software and were creating IT support desk tickets about it in dozens,to which even the young padawans under my care were like "WTF".

Being a developer has nothing to do with Linux knowledge,not to mention most of the devs that work for corporate are just "wait until that coffee break" code-monkeys,copy-pasting random spaghetti code from StackOverflow for a good paycheck. Highly doubtful they would use Linux for anything than a Jenkins server or an Ubuntu/WSL docker base. LMAO.

You need to actually learn an operating system if you want to use it,you need to spend time and learn software if you want to use it,coding skills are nice,but they dont make you instantly good and technically savvy or IT infrastructure savvy for that matter. These skills don't guarantee that you feel at home on a complex Linux system.
