Hi A.P.,
I agree powershell supports automation. However, it so complex and
non-portable
that even learning about it and how to use it takes considerably longer than
learning about Unix automation. It puts a significant burden on developers
to
document their DLL's and make the interfaces permanent. Complexity produces
more
expensive and less reliable software.
BTW, what about the non-major apps? From your view, they are simply excluded
from automation.
In PS, type "help cmdlet" to see
the complexity of each and every command. PS does allow automation, but
it is very expensive because most people will be daunted when trying to
learn how
to solve problems with it, people who know how to write stuff in PS are
more expensive
employees, and development time for asking a simple question like
"Show me the last 5 files read in a directory tree"
can require days or more of research and experimentation.
A help page on almost any cmdlet produces a full page-width
pages of options, many of which lead to further questions about
usage.
Yes, PS automates Windows -- but at what cost?

PS: I should write my book of "Why Windows is not my favorite
operating system" (paraphrasing a famous BTL TM).
PS2: Speaking of complexity and documentation, here is the start
of the printout on an up-to-date MacOS of the command
man ls | less
*NAME ls – list directory contents SYNOPSIS ls
[-@ABCFGHILOPRSTUWabcdefghiklmnopqrstuvwxy1%,] [--color=when] [-D
format] [file ...]*
and the same question about "ls" on Windows 11 powershell:
help ls | less # typed in PS

How did we let this happen?

Do I have to be that guy? I hate windows. I love Unix. But the above isn't
really true. MS has actually done a good job of catching up in that
department. All major apps have Powershell libraries. I envy some features
of Powershell, but I still won't use it unless I have to.
One example is PowerCLI, which is very useful for vSphere automation.
Easier to use than their other language APIs, in my opinion. I could go on
with other examples (Active Directory, MSSQL, Exchange), but I think the
point is made...

anyone could do it - even that kid in Jurassic Park. Today, everything
is GUI and nothing can be automated easily or, most of the time,
not at all.
Unix is an ever shrinking oasis in a desert of
non-automation and
complexity.
It is the loss of automation possibilities that
frustrates me the most
