The problem with shell scripts are that they are objectively badly designed. And I do mean objective--there is no reason to accept that "accidentally delete your home directory" is a sane default behavior for "oops I forgot to set a variable". Any project that attempts to make shell scripts not broken is, by design, going to have break compatibility, because compatibility is insane. Powershell is interesting because it's attempting to introduce a different modality into shell scripts--rather than marshalling data as streams of bytes, you can actually represent the output as, well, data. So that a producer program can say "I'm outputting a list of files" and the consumer can actually handle it as a list of files and easily deal with the fact that maybe files have weird names like " ". A task that, for all the 50 years of experience on UNIX, still requires you to jump through hoops in every other shell script.
