I guess it can go unnoticed, I use Arch so maybe that’s why I got more involved. I remember searching why auto completion didn’t work, then finding out I need to install bash-completions package. After knowing that it makes one curious about how it works. Then the next stage is writing it for my own programs because it obviously won’t come with bash-completions package.
I once wrote a shell (terminal) to watch anime, and I wrote auto completion for different commands on it, it was really nice to just type play then prefix and then tab for auto completion on anime names, and even for episodes I wrote auto completion give me last episode I watched + 1.








I don’t know a lot about other fields but stat people are hired a lot by research institutions. A good statistician can reduce the number of experiments you need to do, being able to test a drug/treatment with 7 people instead of 100 means a lot. They save a lot of money.
Also being able to make inference from past data, incomplete data, use correct math (there is always different ways to solve things) so they don’t make mistakes.
And a lot of people with stat degree join either academia, or other fields that have actual problems and use their background to solve issues.
