Sure, Windows doesn't have "legacy" like VMS or Unix etc, but it's been in use by every day people longer than any other current OS except for MacOS, which really isn't the same OS it launched as, whereas Windows has maintained backwards compatibility (for better for for worse) for decades. So.. Legacy? Why not.

I didn't mean to describe python as "legacy"; it is a great choice for scripting in the year 2023. It's second only to pwsh for that.

I use pwsh on Linux every day.

Anything that isn't a lisp machine is a legacy OS ;-)

I realise I've given offense, for which I'm sorry, but I'm driven not so much to denigrate bash as to advocate for a world where shells are semantic.
