I honestly don't know what I'd do if Solus were discontinued.
Truth be told, I'd probably drop Linux if Solus were discontinued. I'm long-since retired and no longer have a work-related need to use Linux. I use Solus because I like it so much. Solus is fun to use, rock-solid, and the Solus team/community is great. Solus was designed to be a desktop environment, nothing more, and it is near perfect for that purpose.
So who knows? If Solus were discontinued, I might buy a Macbook Air laptop and learn the MacOS environment. Two of my sons have been nagging me about Apple for years and years, and I've never tried it. I like my iPhone, so I'd probably like MacOS, and if iOS is any indication, MacOS will be rock solid and easy on my geezer psyche.
