Without a distro to rally behind I’m personally somewhat skeptical. Ubuntu was the best shot we had but since switching everything over to SNAPs it’s on the slow side. With the number of Windows ads and early end of support for Windows 10 there’s a real opportunity for desktop Linux, but until there’s a well supported distro that genuinely doesn’t require using the terminal I can’t see there being mass adoption.
My grandmother ran Linux for a couple decades until her death at 101 years old. My 80+ year old mom has been running Linux for at least 2 decades. Yes, I’m tech support, but I don’t really have to do anything. It just works.
Any distro that ships KDE/Plasma as its default desktop should do the trick. I’m not personally using it right now but I hear OpenSUSE Tumbleweed is kicking a lot of rear end lately.
It’s not about the distro. Most distros out right now are pretty good. What you need is hardware that lots of people want to buy with Linux installed on it as the default choice. Normal people don’t want to install any OS, be it Linux, Windows, MacOS or BSD. Whatever comes by default, it’s good.
I’m pretty sure that right now the most popular Linux distros are ChromeOS and SteamOS. I wonder why
