I'm a regular Linux user, but I wouldn't know how to get all the data from the Wi-Fi applet using the Command Line. GUI have the advantage of discoverability over CLI: with a GUI I get a bunch of useful info in a single place, with a CLI I first need to know that a data is available and then I need to look-up the right invocation to get this data.

UI also represents an opportunity for standardization, which is a powerful force for onboarding non-technical users and in time, turning them into power users. Standardized patterns illustrate to users that there's a method to the madness and that computers are finite, learnable systems and not seemingly arbitrary chaos or unintelligible techno-wizardry.
