If you want to use Linux without the terminal nowadays it’s pretty easy. But also I think the fear of the terminal is part of the culture that consumer electronics have cultivated where people don’t know (or want to know) how their systems work.
If you take the time to use it, not only can you save yourself time, but also learn a lot more about how you can fix things when they go wrong! That kind of knowledge gives you so much more ownership of your system, because you don’t have to rely on your manufacturer to solve problems for you.
Same for Mac and Windows too, the terminal is something that shouldn’t be necessary, but when it is it helps to know what you’re doing. :)
