dnf and apt are both package managers, they function a bit different. The ppa is a personal repository set up for apt, so it qon't work in combination with dnf. You could try and set up quickgui through the build instructions with the tarball on their github page, but as far as I can read right now quickemu does work on fedora through dnf
Spotify is a good example of this imo, I can listen everything, so it's not necessary to pirate music. I do have some issues, but never had the problem of not being able to listen what I want
You can avoid the level cap with smart combining, but the cap is completely unnecessary in my opinion. Why wouldn't you be allowed to put in 40 levels for something
afaik, doas is a bit more minimal than sudo, so less bloatware. Sudo has a lot of CVE's every year and because doas is way smaller, it has a lot less security issues.
I mostly try to have a lot of projects running at the same time so I can switch around if I'm getting bored with the current project. Also try some mundane things like beacon mining, those really get some creative juices flowing!
I have an Asus vivobook flip, which also has a touchscreen. I daily drive pop OS, which works great with my touchscreen, altough the mouse sometimes dissapears and you need to drag it to the top bar to make it reappear. Screen rotation also works quite good by the way.
If you don't feel the need, don't do it. But linux can give you extra privacy, customizability or a way to tinker with everything on your system. Distros like fedora, linux mint and pop os are great distros to start if you feel the urge some day.
sorry, should've clarified: secure copy, it's an ssh kind of way of copying files to a server
