The point of a shell is not to be an all-powerful programming language.
The point is to allow to simply (with minimal changes to what you have done manually before) automate low-complexity tasks, with minimal extra complexity, in a hands-on way with high visibility into the steps.
Missing the difference between a shell and a programming language is essentially what Powershell embodies - even though there is no doubt that quite a few people on the Linux side have mistaken bash for a programming language.
And *WHY* must they continue to be different or separate? "Because history" isn't a good enough reason. Having one language that's capable of handling simple (shell) and complex (programming) automation tasks isn't a mistake, it's sanity.
And the focus on objects means there is still a lack of good tools to manipulate text.
Ignorance of the tools doesn't mean they don't exist, and 'good' is a subjective term. Based on your logic thus far, I doubt your definition of 'good' will pass with everyone outside of the "MS is evil" club. :P
Plus the Java-style verbosity, leading then to the need for aliases (usually with names that have no connection at all to the long name). Yay for having to learn every command twice, once in long and once in short form.
You don't need to use aliases, you just need to press tab. Autocomplete/intellisense in powershell works not only for the command names, but the parameters and frequently the inputs as well.
Also, complaining about verbosity is sad. It like you're trying to uphold the old greybeard mentality of job security by means of "no-one else knows how to do what I'm doing", or a poor-man's version of closed source by means of unreadable code. Verbosity makes code readable, not just the day you're writing it, but months or years later when you need to fix or update it. In powershell you have the best of both worlds with conciseness through tab-completion AND verbosity. If you compared actual keyboard strokes (instead of characters displayed) between powershell and bash, you might be surprised to find them very comparable.
