I've learnt to become proficient on the Unix command line and vi over 30 years ago (on the company's own System V port, no less!). Best investment ever! Not only is it the environment most suited for development tasks, it also is consistently present on all systems I've worked on since. Navigating around Unix has long become part of my spinal chord/muscle memory. I can't count how many times I've heard the "man, we don't do the command line thing these days" meme. Like in late 90s from Windows fanboys. Or in 2000s from Java geeks who only knew their Java IDE and nothing else. Yet here we are working with clouds, containers, and FaaS based on POSIX principles.
