It's a reimplementation of the Amiga OS, which predates both of the systems you mention by many years.

Microsoft and Apple copied AmigaOS GUI and OS/2 Warp GUI features. Even BeOS had a start menu of sorts.

There's no need to innovate on perfection.

That's how you get the current mainstream operating systems that have minimalized to the point of uselessness and cleaned to the point what is a UI element and what is decoration.

My thoughts exactly.

In my opinion, the mid-1990s to mid-2000s were the pinnacle of GUI design, specifically that of stacking window managers, in terms of usability.

AROS is anything but new OS. It started in 1995.
