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’m sure there are ways to make it more convenient to use a terminal with dyslexia but I’m gonna guess that it’s always going to be a bit of an uphill battle. It might make more sense to use a gui in that case for many applications. Conversly, it’s also good to make sure you have a proper terminal interface as well for disability reasons, but also for the convenience that a terminal interface can provide for people who are familiar with the terminal.
