What an asinine comment. So nobody should ever do anything new because, well, it's already been around for decades in some form or another.
Powershell is different from the UNIX shell environment. In some ways things are more difficult, in others much much easier and cleaner.
What does a neckbeard like you get out of this? Powershell isn't bash and sucks! What I get a kick out of is the plethora of bullshit UNIX shells and how they get a pass, even though they all have their own little quirks. Back when I was stuck on 70's technology, the rule was always use 'sh' for scripts, not csh/tcsh - those can be used for interactive but are poor choices for scripts.
Nowadays? Pfft, people using 'bash', 'sh', 'tcsh', it's a god damn mess. Then you have the cool kids using Python (Perl is so old school now, apparently, though it's 50X better for most routine UNIX scripting).
Don't be a tard, nobody will take you seriously.
