I think it’s still worth learning it as a hobbitst, same thing as the knife skills for someone who likes to cook, you don’t need to be super proficient with a knife, but the basics of knife skills will up your cooking by a lot, at some point you’ll reach diminishing returns and you’ll stop learning, but the basic is almost essential. Same thing for CLI, you don’t need to become a master in the command line, but being comfortable around it will help you a lot. In other words, trying to run a server without CLI is like trying to cook without a knife, is it possible? Depending on what you’re trying to do yes but in general you’re shooting yourself in the foot, just because a blender can replace a knife in some instances doesn’t mean you can use it for all of the same things you would use a knife, a GUI is the blender of servers, it makes some things easier but is not as versatile.
