I couldn't disagree more, I think bash is a horrifically bad programming language. Honestly I'm incredibly surprised anyone could compare PowerShell and bash and think that PowerShell is the arcane one.
Bash is described as a "command language" and not a programming language per se.
Bash is what you use to type in commands, and automate said commands if you need to whip out a quick script that runs what you would otherwise run manually. Bash, scripting-wise, is command line glue.
If all you want to do is run commands with some logic, PowerShell is simply dreadful and outright developer-hostile. I doubt there is a single person on earth who uses PowerShell as a command shell like Bash is used.
This subthread was specifically about programming languages being available out of the box in OSs, so when you brought up bash my natural assumption was that meant as a programming language.
Expand your views. Everyone aren't you, didn't learn the same things as you and understand different things than you.
I learned some C++ as my first language, therefore I got stuck in an object oriented mindset, this translates really well to PowerShell and really poorly to bash. The thing where everything is text doesn't make sense, text isn't stable and everyone will write their own partially broken parsing implementation. In PowerShell they try to make everything an object, with type checking and other goodies, solid autocomplete for scripts being one.
In PowerShell I can deserialise JSON and perform CRUD operations on the data easily.
I'd say powershell is outright developer friendly as it brings a production grade language to the scripting table.
If powershell could parse bash completion files and integrate sudo better I'd use it as a command shell on all platforms, which right now are limited to MacOS and Linux.
PowerShell is such joy that it should be there on any Linux as default interactive shell.
