Absolutely!

First, terminal is, for the most part, distro- and DE-agnostic. Unless you use something specific to the distro or DE (like package management or working with DE dependencies), what would work on one Linux system would also work on the other. This allows you to immediately get a grasp of any Linux system.

Second, terminal is fast. You can search through GUI for all eternity, or you can type one line that does what you want, saving tons of time in the process.

With that said, both GUI and terminal should develop hand in hand to provide a user experience that suits both regular and power users alike. Windows commonly shifts to the side of regular user, while making it harder for power users to do what they want. Linux as it was in the old days shifted towards power users.

Nowadays, I think Linux finally strikes the right balance - it is accessible and powerful at the same time.
