I didn’t mean that PS is the ideal shell, it has plenty of warts (I did mention the Verb-Noun thing), and bash’s syntax does have a good subset — namely piping, redirects to a certain degree. But variable substitution, not having proper math support, everything is text are terrible and they do come up with the arguably rare, more complex commands. Also, having a convention that has quite a few edge cases where it doesn’t work good may still be better than not having any. And the application not creating good cli is not shell-specific at all —- the linux world has it better because a good cli is prioritized. Even though git is often touted as having a terrible interface.
