Zsh is a great replacement for Bash that uses far superior internal code architecture and an overall better design, but Bash is (still) the default on millions (if not billions) of systems (even though Apple, Kali, Manjaro, and other Arch distros have moved to Zsh).
I simply choose to keep my muscle-memory and configuration knowledge compatible with the defaults I use at work every day rather than have to remember two things, specifically simple prompts, exported functions, and less surprises like using zshrc v.s. zshenv (the difference really matters to vi users especially).
Oh yeah, oh-my-fucking-zsh is a butt-ugly monstrosity that the Zsh team even says should not be used partly because it is incredibly inefficient and scientifically proven to make you less productive. If you like it fine, but I prefer minimalism.
My sincere thanks to those who patiently helped me through this experiment. The discover of autoloaded functions was a very significant discovery (for me). -- Watch live at https://www.twitch.tv/rwxrob
