Companies hiring the people probably also have a need if they are hiring and looking to grow and scale out. I made a "you don't need X / Y / Z" point because I strongly believe most people don't need these tools and really need a better understanding of Linux basics. You can also learn these tools on your own if they're mentioned in job descriptions of jobs you're applying for, but that doesn't mean you have to use them when you're the decision maker, or for a personal project.

Using these tools in personal projects is how you learn them though, so you can talk about your experience, and maybe even show some prototype in an interview / CV etc.
