This is the main reason that, even though I know I'd enjoy zsh, I stubbornly stick with bash. It's because I know that I will be extra frustrated when I have to log into any of the number of machines that I have to do real work on that don't have it already set up.
That’s like saying: “This is the main reason that, even though I know I’d enjoy a nice car, I stubbornly stick with a run-down PT Cruiser without radio and air conditioning. It’s because I know that I will be extra frustrated when I have to take an Uber.”
I personally use zsh and do not want to miss it on my own machines. I however do log in onto machines that sometimes do not even have bash (yeah it’s rare nowadays, but it exists), and I adapt just fine. It’s not super pleasant, but not using zsh on my machines would be less pleasant.
