It's also both a larger download and slower to start than Java, which is not known for being light and nimble. In fact, PowerShell is so slow that you can both compile and run the equivalent C# program before PowerShell finishes launching. Not ideal for a shell or a scripting language.

Also, the newer versions aren't included with Windows, which would have been useful – instead Windows includes an incompatible older version that admonishes you to download the new version. But why would you download several hundred megabytes of pwsh when you can equally well download any other language runtime?

Also, it sends "telemetry" to Microsoft by default.

Also, the error handling is just awful, silencing errors by default, requiring several different incantations to fix.

Also, the documentation is vague and useless. And the syntax is ugly.
