It's just useful to know the name of the app sometimes. With ubuntu default options, "Text Editor" (in the GUI menu), is "gedit" for example. "File Browser" is "Nautilus". These things are actually not easy to learn if you aren't deep into the Linux world.
On Windows, I would never need to know that the "File browser window" is called "explorer" to do anything with it.
I'm not a child with a machine gun, I just don't want to go to the terminal every time.
