ELI5: Why are most hacking tools still built on CMD and version of UNIX?

I'm currently taking an Global informations technology course and during my studies I took some extra time to look into WiFi password cracking and vulnerability exploits for many different situations. The one thing I noticed over and over again is that most of the tools either come on an OS like Kali or Backtrack or need to be downloaded and ran through CMD. 

Why is it that no one has bothered to make top line attacking exploits with a GUI?

Multiple reasons. The biggest one: GUIs are a pain in the ass to make.

Other than that - when working with CLI-tools you have text as in- and output, which you can properly parse and pipe into other tools. GUI applications could also output their data to stdout, but why go this way if all you need to do are giving some options anyway?

Third reason - keyboard is faster than a mouse. If you know what you need you'll be way faster by typing it (and additionally it will be even more faster with completion) than with clicking through a gui.
