Yes. Like all those early car buyers would be perfectly happy with faster horses.
That being said I really don't mind that MS went the PowerShell route. It improved their ecosystem a lot and I belive was also one of the engines behind the more open minded move towards open source...maybe someone at MS can chime in but I feel like PS was always one of the strong projects pushing that forward from talking to some MS engineers.
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.
Powershell ideas go back to how REPLs work in those environments.
