Mh, it probably depends a lot where you're coming from. I don't need Powershell or have a reason to learn it in my daily work, and I mostly use WSL to access Linux shells everywhere else. And on top of that, I don't understand why Powershell needs a completely different command set to basically every other shell. It's a biased take, but I have not had an interaction with Powershell that I liked, nor have I seen a feature that made me want to look into it more.
What's the killer feature, would you say? Care giving me the fanboy-pitch?
edit. Oh and I forgot, the tab completion in Powershell is so incredibly dumb. I never ever in my life want to cycle through all items in a path, and much less have it be case insensitive. Come to think of it, this might be the origin of most of my disdain. ;)
That actually makes a lot of sense. I never even second guessed how tedious all the parsing is. But then, as others have said here, as soon as the task at hand reaches a level of complexity beyond grepping, piping and so on I just very naturally move to Python.
On a different note, there are ways to teach bash json. I recall seeing a hacker conference talk on it some time ago, but didn't pay close attention.
