Or to the point of the original parent: the industry considers powershell a solution in search of a problem.
PowerShell, or at least the concept behind PowerShel, is an improvement/superset over the Unix shells -- and can do whatever the shells can do, plus stuff they cannot do, because they don't support typed entities.
Its problems are not technical or conceptual -- they are ecosystem and historical: lack of compatible tools, windows-only, etc.
