My brother is 12 and just like other people of his age he can’t use a computer properly because he is only familiar with mobile devices and dumbed-down computers
I recently dual-booted Fedora KDE and Windows 10 on his laptop. Showed him Discovery and told him, “This is the app store. Everything you’ll ever need is here, and if you can’t find something just tell me and I’ll add it there”. I also set up bottles telling him “Your non-steam games are here”. He installed Steam and other apps himself
I guess he is a better Linux user than Linus Sebastian since he installed Steam without breaking his OS…
The tech support questions and stuff like “Can you install this for me?” or “Is this a virus?” dropped to zero. He only asks me things like “What was the name of PowerPoint for Linux” once in a while
After a week I have hardly ever seen my brother use Windows. He says Fedora is “like iOS” and he absolutely loved it
I use Arch and he keeps telling me “Why are you doing that nerdy terminal stuff just use Fedora”. He also keeps explaining to me why Fedora better than my “nerd OS”
I only have one machine left in use with a single disk shared between the two systems (a laptop) but I haven’t seen that happen for quite some time now (years really, and never on the last two laptops). And it hasn’t happened for a very long time in my main box that has several drives, where Windows gets its own little drive and Linux has the others (back when it happened, it was simpler in that case as I could use the BIOS boot manager to pick a drive to boot from). I don’t boot Windows very often, maybe once a month to run updates, and nothing much happens.
So while it certainly was a problem at some point, I don’t think it still is.
