I kinda figured out that although youtubers attempt to make you feel a has-been if you don't use all the bells and whistles that come with zsh, that Bash does everything I need, and I can extend it if needed.
Minimalism might be my aim, but it's not a do of die mantra, even so zsh appears rather flash and with esoteric possibilies that I will never use.
I'm also keeping my bash scripts, there seems to be little point in making them reliant on some other shell.
There are also a number of things that can improve your bash "experience" like Bash Line Editor
So I'm sticking to Bash for now.
