What we should have been doing is supporting nature to help us survive climate change.
It's really not clear at all what you mean by this.
Linux is mainly for coders and hobbyist system builders; most people doing actual work can't be arsed
Linux is the most common operating system around (Android). BSD is right after (iOS). Windows is a distant third.
As for GNU/Linux (not Android), most people who use it, use it for real work. It's a programmer's OS.
Why?...because fucking management is dumb AF....at the end of the day, I need a paycheck.
Management isn't dumb. They have incentives that are different than yours, and they chase their own incentives.
Not evangelizing Ruby,
You should, it's a great language.
It definitely is much more effort and takes more skill and experience to respect KISS than just heap complexity on complexity
It doesn't take more effort (it does take more skill). Some people say it takes more time up front, and that may be true, but it pays off within days if not hours or even minutes (meaning total time required is less).
There are several reasons for this:
1) A major part of KISS is reducing redundancy. You are literally writing fewer lines of code.
2) The benefit of refactoring tends to begin earlier rather than later (ie, move your methods around, rename variables) within the first 500 lines of code.
3) Most of the time of software development is in testing. Well written code requires less testing.
etc
The problem with "management" is that management is dumb and often greedy and cannot do long-term planning.
They can do long term planning, but their incentives are about doing things that improve their own career. (If you want people to change, their incentives need to change).
Never trust an operating system.
