PowerShell is underrated, but it's its own worst enemy, stubbornly insisting on LongForm-VerbNoun syntax for all but the most common commands that anyone familiar with the shell would expect. A few UI touchups and it could go substantially further, especially as MS continues quietly gutting the NT heritage out of Win10 and integrating more and more nix-like features, including full Linux kernel emulation, all so you can run Docker without a VM! What a world.

I continue to believe that within 10 years, Microsoft will have just switched entirely to Linux+WINE under the covers. :)
