It's a database server, not a telephone. I don't want to press 3 for system operator messages. I don't want to put a 4 next to a job and kill it.
I don't want doing tasks to be "Press 1 3 4 5 3 3 3 4 4 4 4 4 4 9 9 12 tab tab enter a date, press f7, then type ws put a 2 next to the print job you want and type outq($printer_name)." I don't want to screw around with twinax terminals. I don't want to screw around with varying things on and off. Don't get me wrong, it's not that I'm against CLIs, I am the biggest linux/bsd fan you're ever going to find, and I consider an X server an annoyance for most things, it's just that I'm against *FREAKING HORRIBLE* CLIs (it's not even a CLI, what the hell is it? nobody knows)
