Bash is 27 years old. It was written to replace the Bourne shell, which is 39.
It is not terribly surprising that a 9 year old tool like Powershell made some improvements over an earlier tool that was already old enough to vote!

RE - your aside '\' vs '/' - I think most of us still shake our head at that decision.

That decision goes back to MS-DOS 2.11, circa 1983. (DOS 1.0 didn't have subdirectories.) The model for DOS directories came from UNIX, which at that time was the very aggressively defended intellectual property of AT&T. As Microsoft was an AT&T licensee -- for Xenix, their version of AT&T System 7 UNIX, which was Microsoft's vision of the future of operating systems when PCs became powerful enough: they licensed it in 1978 and resold it via OEMs -- I speculate that they were afraid that AT&T might sue them for patent or copyright violation relating to the filesystem design if they went with a forward slash.

You know you can use both since like XP, right? You can even mix them up in one path which can look quite confusing c:/windows\system32/etc/drivers\
Secondly, what constitutes an improvement is a matter of opinion. For example, I don't see this Powersell as an improvement at all.
Cmdlets tell the shell their parameters, and their parameters are long names, so you can just tab through them to find a) the available parameters and b) the ones which might help you.
Also, Bash does have a way of doing it the Powershell-way, if you want that, as others have commented.
Which is also why I disagree with your statement. Bash may be old, but neither the underlying technology nor the use-case changed much in that time. So, there is not a whole lot where you can innovate with a new tool, at least not for such basic tasks, and instead, Bash has matured throughout 27 years to perfectly fit that underlying technology and use-case that millions of people have.
