I would have Debian go back in time to 1999 and adopt Window Maker as it's default DE. GNUstep would be integrated and made cross platform. All popular software on windows, Mac and Linux would be based off of it. We'd be used to lightning fast, beautiful DE, with an auto docking paradigm. World peace and the end of hunger would be achieved.
Wouldn’t you have to get GNUstep working first? That seems like a limiting factor in your otherwise admirable plan.
macOS and Linux could indeed have had a common
Desktop API. GNUstep was started even before Cacoa and could have kept compatibility with it.
The other problem is that no GNUstep desktop environment ever really got off the ground either. WindowMaker ( really just a window manager, not a DE ) is not written in GNUstep. I imagine it is written in C against the X11 libs.
I like your dream though. I used to dream of the same.
I am pretty sure that GNUstep is cross platform though. At least we have that.
It's a pie in the sky by definition. It was the *Step paradigm I had fallen in love with. Very elegant. Mail.app was cool. It's not the paradigm the industry adopted, in the end. MDI and Taskbar won for better or worse. Just look at the upheaval that Gnome caused by abandoning it, the sheer number of forks.
I miss my Window Maker that came rizzed up to nines by default on Conectiva. It made my 486 fast, elegant, and futuristic. I could listen to MP3, chat on IRC, and have a page open on Netscape all at the same time!
BTW GNUstep is alive. I'll check out NextSpace, thanks for pointing me there!
