ReactOS is trying to make a Windows type OS and needs developers and donations.

HakuOS is a BEOS clone.

AROS is and AmigaOS clone.

OSFree is an OS/2 clone.

Nobody has solved how to make a free or open source operating system that uses apps and drivers from the original.

Having FOSS alternatives to those OSes is just as important that *BSD Unix, Linux, and MacOS are alternatives to Unix that can run Unix apps due to the API.

There are always problems to be solved like getting everyone solar panels on their house to fight climate change and cut down on their electric bill.

Ask SpaceX why one of their rockets blew up recently. Someone needs to solve that problem too.
