“To bring a MicroVAX to its knees, try twenty users running vi — or four running EMACS.”
I just couldn’t help but smile, nod, and laugh lol. Vi is a fairly light weight program in todays world, and was designed in a time when just moving your text editors cursor was probably slow as watching paint drying. Emacs on the other hand, tends to be rather hefty in most good implementations, I think it was once a cottage indrusty to make light-weight emacsen.
And to this day in the form of GNU and X Emacs is, one small operating system, but a huge text editor compared to the nimble Vi. I don’t go much in for the Vi Vs. Emacs stuff and vice versa, because I use the Vim which is the only thing better then Vi 😉
