Times have really changed, especially in the past five years. Even completely tech-agnostic people use GNU/Linux in my family. Reason is "Because it just works." no more Windows installing things that you hate. No more advertisements in the start menu or file manager. No more screenshots every five seconds. No more Windows slowing down the computer gradually. A relative's computer was unusable because of Windows, because it has slowed down the computer so much that the start menu took 10 seconds to open. All she did was her net banking, text editing and some very light photo editing. Ever since switching to GNU/Linux, her computer works again normally. And all of the tech questions about weird things like programmes randomly not starting have disappeared.
Also, nowadays you really never have to touch the command line. You can use an App-Store-like experience to install your programmes, just like you would on a phone. It also handles all updates automatically. This alone makes it such a better, "normie" operating system than Windows. Hit "update all", and it updates all of your packages for the system, the kernel itself, drivers, the apps themselves, literally everything. Because try explaining grandma, she needs to update the system, then the drivers, then every single application separately. Now you can tell Grandma instead: "Press this button and wait for 20 minutes."
The difference is night and day. Old computers work normally again. You don't need such overkill configurations like most Windows computers have to just run your text editing on net banking. By now it is objectively better.
If you're new, just use one of the many pre-configured options. No need to tinker with your system if you don't want to. Just install one of the literally hundreds "just works" distros that package everything for you.
Lastly, I'm going to say it is no exaggeration if I say installing GNU/Linux has solved literally every single issue people in my family had with computers. Because now it just works. No bloat, no nonsense. Just a computer.
