And note also that Teletypes and paper tape were the rationale for the ultimate "you asked for it, you got it" text editor - TECO. The basic idea was, if you had a paper tape with typographical errors, you could feed that and a correction tape into TECO, and it would apply the corrections. It eventually morphed into an all-purpose editor; DEC's VTEDIT was a screen-oriented editor written in TECO macros, and Emacs was originally implemented in TECO as well. It's kind of appropriate that a typical TECO command line looks a lot like transmission line noise. :)
